![How to Choose an MCP Search Service for AI Agents: A Comparison of 5 Providers](https://cdn.anysearch.com/content/image/2026/11/11/fb4adcf8bd53455c-20261111-160835.jpg)

This article compares five search MCP services for AI Agents: AnySearch, Exa, Firecrawl, Parallel, and Tavily. It examines the tasks each service is designed to support, the types of information it can retrieve, and how to get started with each MCP.

**For industry research that requires both general web search and specialized information retrieval across multiple domains, AnySearch is a strong option.** AnySearch provides general web search, specialized domain search, batch search, and webpage content extraction through a single MCP interface. This makes it easier to search for and review different types of information related to a single research question.

Parallel is worth considering when you need to find information in government PDFs or lengthy reports.

Exa is worth considering when you want to submit a research question and receive an initial answer with cited sources.

Firecrawl is worth considering when you need to retrieve futures quotes and verify contract months and update timestamps.

Tavily is worth considering when you need to filter search results before retrieving content from multiple webpages in batches.

The following sections explain the reasons behind these recommendations, based on each provider's officially documented product capabilities and research using the same questions.

## **Choose a Search MCP Based on Your Work Requirements**

The table below lists one search MCP to try first for each type of work, with explanations based on the Hormuz impact analysis discussed later in this article. The five services have overlapping capabilities, and each row presents a use case where one service is worth trying first.

| What You Need to Do | Which MCP to Try First | Why Choose It |
| --- | --- | --- |
| Conduct industry research that requires both general web search and specialized information retrieval across multiple domains. | AnySearch | Provides general web search, specialized domain search, batch search, and webpage content extraction through a single MCP interface. It allows multiple types of queries to be submitted at once, followed by further retrieval of source content, making it easier to gather information from different domains for a research topic. |
| Submit a complete research question and get an initial answer with cited sources. | Exa | Its research tool can perform multi-step searches and organize information before returning an initial research draft. In this research, additional searches were conducted to find data missing from the initial draft. |
| Look up futures quotes and verify contract months and update timestamps. | Firecrawl | The market data tool used in this test provided contract months, update timestamps, and latency information, making it easier to confirm which products the quotes were for and when they were updated. |
| Find information in government PDFs or lengthy reports. | Parallel | Fetch can return relevant excerpts first or provide the full text upon request. Both methods were used to retrieve information from a USDA report in this research. |
| Filter search results first, then retrieve content from multiple webpages in batches. | Tavily | Search finds sources, while Extract retrieves content from selected URLs in batches. This is suitable when you want to decide which content to read next. |

Choose the search services to try based on the most common everyday tasks, then compare the information returned by each service using the same business question. The comparison focuses on whether key sources can be found, whether all the required information can be retrieved, and how much more information needs to be searched for.

## **What the Five Services Offer and Who They Are For**

When choosing a service, first look at the capabilities each provider offers and how they can be used in actual research. The following sections outline the core capabilities of each provider's MCP based on official documentation. They then examine the same question about the impact of the Strait of Hormuz, showing which tools were used and what information was retrieved in this test.

### **Official Core Capabilities**

The table below summarizes the core capabilities and main tools listed on each provider's official website. The tools available may vary depending on account permissions and enabled settings.

| Provider | Official Core MCP Capabilities | Main Tools | Main Use Cases |
| --- | --- | --- | --- |
| AnySearch | General web search, cross-domain specialized information retrieval, domain directory and parameter lookup, parallel batch search, and webpage content extraction | Search, Sub-domains, Batch Search, Extract | Combine general search and specialized queries through a single interface, collect information from different domains in batches, and then read the source content. |
| Exa | Web search, webpage retrieval, multi-step research, and structured output; advanced search is also available | Search, Fetch, Research; optional Advanced Search | Find and retrieve webpage content, submit research tasks, and obtain results with sources or in a specified format. |
| Firecrawl | Web search and scraping, website link discovery, file parsing, structured data extraction, and browser interaction; specialized data tools are also available depending on permissions | Search, Scrape, Map, Parse, Find Tools; additional browser interaction tools | Retrieve webpage or file content, collect website information, and extract information based on specified fields. |
| Parallel | Web search and webpage content retrieval, research answers with sources, batch webpage fact-checking, and specialized domain discovery and retrieval | Search, Fetch, Research, Decisions, and specialized domain search tools | Find information in webpages and lengthy reports, generate research answers, or search for data in specific domains. |
| Tavily | Web search, content extraction, website mapping, website crawling, and research tasks | Search, Extract, Map, Crawl, Research | Collect webpage information, retrieve content from multiple webpages in batches, organize website content, or conduct research. |

### **How the Five Services Were Used in the Same Case Study**

To show how these tools are used in research, this article compares records from the five services based on the same question about the impact of the Strait of Hormuz. The task required information on crude oil and gold prices, U.S. energy inventories, food supply and demand, and congressional records. It covered several specialized domains and required both searching for and reading official sources. The full question is provided in the case study below.

The five records differ in execution time, follow-up prompts, tool permissions, and budget. The following sections show how each service was actually used.

### **AnySearch: Suitable for General Web Search and Cross-Domain Specialized Information Retrieval**

A research task often requires understanding the background of an event, as well as looking up market prices, industry statistics, or regulations. AnySearch provides general web search and specialized domain search through a single MCP interface. Users can first check available domains and parameters, then submit different queries in batches. When more details are needed, they can continue extracting the full text of source webpages. This combination is suitable for teams that need to gather different types of information around one research question and carry out research step by step.

In the Strait of Hormuz case study, market data queries required specifying the products, energy research required looking up inventories and production separately, food supply and demand queries required specifying the year, and legislative research required checking the progress of bills. The Agent used AnySearch to search for each type of information separately, then read sources such as the EIA, USDA, and Congress.gov and used information from different domains in the same impact analysis.

After specialized domain searches provided leads, the Agent continued using AnySearch's general web search to find agency reports. It then used webpage content extraction to read data explanations and official documents. All these searches and follow-up searches were completed through the same MCP interface, making it easier to gather more information as needed. The case study below describes this process in detail.

### **Exa: Suitable for Getting an Initial Research Draft, Then Checking and Adding Information**

With Exa's Research tool, users can submit a complete research question. Exa searches for and organizes information, then returns an initial answer. This approach is suitable for teams that want the service to handle information gathering and initial organization. Generating an initial research draft requires waiting for the information to be organized, making it more suitable for topic research and first drafts of reports.

In the Strait of Hormuz case study, the original question asked for global wheat production. However, Exa's initial draft mainly provided total supply and noted that it included beginning stocks. Production refers to the amount of grain produced in a given year, while total supply also includes stocks. These are two different measures and answer different questions. Additional searches were needed to find the production data. Therefore, before using an initial research draft, it is important to check whether all the required data is included and whether it meets the requirements of the question.

### **Firecrawl: Suitable for Checking Futures Quotes, Searching, and Reading Webpages**

In this research, the market data tool used through Firecrawl returned futures contract months, quote update times, and latency information. AnySearch, by comparison, retrieved prices, previous closing prices, and price ranges through its financial domain search. The two services provide different types of information. When choosing a service, these differences should be checked against actual business needs.

Firecrawl also supports searching for information and reading the original content. First, use Search to find sources, then use Scrape to read the selected sources. In this research, these two tools were used to retrieve the text of a USDA report and EIA data files. Find Tools was then used to locate a market data tool and look up futures quotes.

### **Parallel: Suitable for Finding Information in PDFs and Lengthy Reports**

Parallel's Fetch tool can first return excerpts related to a query. If more context is needed, users can request the full text. In the Strait of Hormuz research, both methods were used to read the same USDA PDF. This is suitable for teams that often need to find data in government reports and read the original text to check the data's scope and meaning. When testing the service, pay attention to whether the required paragraphs, tables, and explanations are complete.

In addition to reading reports directly, Parallel's Research tool can also prepare an initial answer with citations, providing a starting point for checking the sources. In this case study, after receiving the initial draft, additional searches were made using Search and Fetch to read historical news reports and check which events and dates were associated with the crude oil price increase.

### **Tavily: Suitable for Building Your Own Information-Gathering Workflow with Search and Batch Extraction**

Tavily's Search and Extract tools can be used in an information-gathering workflow managed by the Agent itself: first search for leads, then select the URLs to keep, and finally retrieve content from those URLs in batches. In the Strait of Hormuz research, this process was used to retrieve materials such as USDA PDF and EIA CSV files. For Agents that can already break down questions and select sources, these tools can handle the search and webpage retrieval tasks.

When using these tools, consider the time needed to retrieve missing content and retry failed requests. In the Strait of Hormuz case study, one batch contained four URLs. Three returned content, while one failed. Some other requests were also rate-limited and had to be retried after waiting. As a result, the research required additional attempts to retrieve content from failed pages. When testing Tavily, check whether your own tasks also require these extra steps and how they affect the time needed to complete the task.

## **Case Study: How an Agent Uses AnySearch for Cross-Domain Research**

The case study was recorded on November 6, 2026. The original question was:

> The U.S. and Iran have started fighting in the Strait of Hormuz, and oil prices have surged . Help me prepare a full impact analysis. What are the latest price movements for Brent crude, WTI crude oil, and gold? How much remains in the U.S. Strategic Petroleum Reserve, and what are the current production and inventory levels? Will this rise in oil prices spread to global food prices? What are the production and trade figures for wheat and rice? Has the U.S. Congress taken any legislative action or made any moves to authorize the war? Finally, bring these four areas together to assess the overall impact of the conflict and the sectors it could affect.

The event described in the question and the rise in oil prices are also points to be verified in this research.

The question clearly sets out four areas to investigate: market prices, energy, food, and the U.S. Congress. Based on these requirements, the Agent arranged the searches and used the AnySearch MCP to gather information and carry out the analysis. The following sections explain the process in three steps: searching, follow-up searches, and organizing the findings.

### **Step 1: Choose the Search Approach Based on the Type of Information**

The Agent first checked the domains and parameters available through AnySearch, then set different search conditions for each type of information: specifying the products for market prices, looking up inventories and production separately for energy data, specifying the year for food supply and demand, and looking up bills and voting progress in congressional records. It then submitted the queries through Batch Search and used general web search to find additional leads.

| Information Needed | How to Search and Retrieve It | How to Organize It for the Analysis |
| --- | --- | --- |
| Crude oil and gold prices | Retrieve prices, previous closes, price changes, and price ranges by product, then search for related news reports. | Record the quote sources and the time of retrieval. Keep the prices retrieved in this search separate from historical price changes. |
| U.S. strategic reserves, commercial inventories, and production | Search energy data, then retrieve EIA summary text, JSON data, and weekly reports. | List inventory levels and daily production separately by reporting week and unit to avoid mixing different measures. |
| Wheat and rice production and trade | Use AnySearch to search USDA and FAO sources, and extract contents such as WASDE text. | Organize production, trade, and stocks by agency and year. Distinguish forecasts from estimates. |
| U.S. congressional actions | Search for legislative leads, then check action records on Congress.gov and text from GovInfo. | List the progress of each specific measure and distinguish between introduction, passage, and entry into force. |

> Note: The information in the table was collected through AnySearch. The Agent prepared the final impact analysis after reading and checking these sources.

### **Step 2: Combine Web Search and Webpage Content Extraction to Find Additional Official Sources**

The Agent first used AnySearch's specialized domain search to find relevant information, then used its general web search and webpage content extraction capabilities to find additional information from official sources to fill data gaps. For energy data, it continued searching for EIA weekly reports, summary text, and data access points. For food data, it searched for USDA and FAO reports. For congressional records, it read action records on Congress.gov and official texts from GovInfo.

These materials were used to check the reporting periods, what the data measures mean, and the progress of bills. General web search helped locate additional sources, while webpage content extraction made it easier to read explanations beyond the summaries. This allowed information from different domains to be used in the subsequent analysis.

### **Step 3: Organize Information by Source and Reporting Period to Prepare an Impact Analysis**

After retrieving the information, the Agent organized the data by source, reporting period, and unit. For energy data, it kept inventory levels separate from daily production. For food data, it organized production, trade, and stocks separately and distinguished estimates from forecasts. For congressional records, it distinguished between bill introduction, voting, and enactment status.

The organized information was used to analyze how changes in oil prices could affect transportation, fertilizers, food, and macroeconomic and financial conditions. The Agent also considered different scenarios based on inventory buffers and policy actions. This case shows how AnySearch uses general web search, specialized domain search, and webpage content extraction to continue providing information for cross-domain research.

When testing the service, you can submit a complete work-related question through a client connected to AnySearch. Check whether the final answer covers the main requirements and whether key findings can be traced to specific sources. This makes it easier to understand how these capabilities can support everyday research than testing a single keyword.

## **AnySearch MCP Setup: No Local Deployment Required, Get Started in Three Steps**

AnySearch provides a hosted remote MCP service that can be connected to through clients that support remote HTTP. **You do not need to deploy a search service locally or install a protocol-conversion proxy. You can also try Search, domain search, Batch Search, and webpage content extraction anonymously, without registering an account or preparing an API key.** If you need more requests, you can configure an account API key.

The official website provides setup instructions for the following 10 clients, with different installation options for each client:

| Client | How to Get Started Quickly |
| --- | --- |
| Cursor, VS Code | On the [official website](https://www.anysearch.com/), go to the Get Started section, select MCP and the corresponding client, then click Install with one click. Follow the client's prompts to confirm the addition. No manual configuration is required. |
| Claude Code, Codex | The official website provides an Open install prompt option. Use the prompt to guide the client through setup. |
| OpenCode, Cline, Google Antigravity, DeepSeek Harness, Hermes Agent, OMP (Oh My Pi) | The setup documentation for each client provides the configuration file location, configuration snippets you can copy, and verification steps. Choose according to the client you are using. |

When using Cursor or VS Code, you can start with one-click installation. If you prefer to manage the configuration yourself, the following section explains how to connect in three steps, using VS Code as an example.

### **Step 1: Copy the Configuration and Connect to the Remote Service**

Create or merge `.vscode/mcp.json` in your workspace, then add the anonymous configuration below. The service endpoint is [`https://api.anysearch.com/mcp`](https://api.anysearch.com/mcp), and it uses Streamable HTTP:

```
{
  "servers": {
    "anysearch": {
      "type": "http",
      "url": "https://api.anysearch.com/mcp",
      "headers": {
        "X-Anysearch-Client": "mcp/1.0.0"
      }
    }
  }
}
```

Anonymous access does not require an API key. If you already have an API key, you can expand the API key configuration below. VS Code will prompt you to enter the key the first time you start the service, so you do not need to write it into the configuration file.

View the full configuration with an API key:

```
{
  "inputs": [
    {
      "type": "promptString",
      "id": "anysearch-api-key",
      "description": "AnySearch API key",
      "password": true
    }
  ],
  "servers": {
    "anysearch": {
      "type": "http",
      "url": "https://api.anysearch.com/mcp",
      "headers": {
        "Authorization": "Bearer ${input:anysearch-api-key}",
        "X-Anysearch-Client": "mcp/1.0.0"
      }
    }
  }
}
```

### **Step 2: Start the Connection in the Client**

Open the VS Code Command Palette, run `MCP: List Servers,` and select `anysearch` → `Start`. Anonymous mode can be started directly.

If you are using an API key, enter it when prompted. Use `Show Output` to check the connection status and confirm that the tools are available. For other clients, follow the corresponding configuration and startup steps in the [official installation documentation](https://www.anysearch.com/docs/mcp-install).

### **Step 3: Ask a Question and Run Your First Search**

After connecting, enter the following prompt in the client's chat:

> Use AnySearch to search the official MCP documentation and return the titles and links of three results.

Once the client calls `search` and returns source links, the first search is complete. You can then ask your own questions, and the client will call domain search, Batch Search, and webpage content extraction as needed.

View examples of domain search, actual search results, and webpage content extraction

When you need to search for a specialized domain, first use `get_sub_domains` to check which parameters are valid, then call `search`. Here, the official React documentation is used as an example: first, look up the code domain, then search for the dependencies and cleanup function in `useEffect`. The following shows the `search` parameters from an existing call:

```
{
  "query": "React useEffect cleanup dependencies official documentation",
  "domain": "code",
  "sub_domain": "code.doc",
  "sub_domain_params": {
    "library": "react"
  },
  "max_results": 3
}
```

The example search returned two results from the official React documentation repository, each with a title, URL, summary, and request ID. The two results point to:

- Example of a useEffect cleanup function.
- Explanation of declaring reactive dependencies.

You can then submit the URL of a selected HTML webpage to extract its content. You can also use the AnySearch installation page to test the extraction feature separately. The parameters are as follows:

```
{
  "url": "https://www.anysearch.com/docs/mcp-install"
}
```

The existing call for the installation page returned the URL, title, and page content.

## **How to Get Started and Calculate Usage Costs**

First, check how to connect to each service, then look at how searches, webpage retrieval, and research answers are measured. In the table below, "anonymous trial" means connecting without signing in or providing an API key. AnySearch Free, Pro, and Enterprise are plans available to registered users. The table summarizes how to get started with each service.

| Service | How to Get Started | What to Check When Calculating Costs |
| --- | --- | --- |
| AnySearch | Try it anonymously. After registration, use an API key and choose the Free, Pro, or Enterprise plan. | Search and extraction are charged per call. The usage in this example is estimated at 95 quota units. See the breakdown below. |
| Exa | Search and webpage retrieval are available for anonymous trials with rate limits. The Research tool requires sign-in or an API key. | One Research task in this example returned a cost of $0.10. Other search, retrieval, and caller-side model costs are charged separately. |
| Firecrawl | Search / Scrape / Parse are available for limited anonymous trials. After signing in or using an API key, the available tools depend on the team's plan. | The 50 tool calls in this example used 96 credits. The cost depends on the credit price under the selected plan. |
| Parallel | Basic tools are available for anonymous trials with rate limits. Research requires authentication. | Search, retrieval, and Research usage are counted separately and calculated according to account rules. |
| Tavily | An anonymous access option is available. Users can also sign in or use an API key. Available features are described in the documentation. | Search and extraction in this example are estimated to cost about $0.328 based on the public pay-as-you-go rates. See the breakdown below. |

A single batch search may contain multiple queries, and a single research answer may involve multiple rounds of internal searches. To estimate costs, count usage according to each provider's billing rules, then add other costs, such as those for the caller-side model.

### **Usage and Cost Estimates for the Same Case Study**

Using the Strait of Hormuz research question from the previous sections, this section estimates the search and extraction costs for AnySearch and Tavily. AnySearch uses the Pro prepaid package rate, while Tavily uses its public pay-as-you-go rate. Neither estimate deducts free allowances. First, look at how each step is charged, then compare the results with your own usage and plan.

### **AnySearch: Estimated Search and Extraction Quota**

According to the product documentation, each successful search sub-query that returns non-empty results counts as one unit, and each valid webpage content extraction counts as one unit. Failed, timed-out, and invalid requests are not charged. Applying these rules to the records from this case study gives the following search and extraction totals:

| Capability | Usage in This Case Study | Estimated Quota Based on Billing Rules |
| --- | --- | --- |
| Batch Search | 16 calls containing 74 sub-queries, all returning non-empty results | 74 units |
| Webpage content extraction: successful | 21 calls | Estimated at 21 units based on effective extraction |
| Webpage content extraction: failed | 14 calls | 0 |
| **Search and extraction total** | **74 search sub-queries + 21 successful extractions** | **About 95 units** |

If all usage is covered by purchased Pro quota at $3 per 1,000 units, the estimated cost of the search and extraction above is **about $0.285**. This is an estimate of tool usage costs based on the call records. Actual charges are subject to the account's usage records.

### **Tavily: Estimated Advanced Search and Webpage Extraction Costs**

In the same research task, Tavily completed 15 Advanced Search calls and successfully extracted content from 29 URLs. According to its public pricing rules, each Advanced Search call costs 2 credits; Advanced Extract costs 2 credits per 5 successful URLs, while Basic Extract costs 1 credit per 5 successful URLs. Based on the number of successful URLs, the estimated usage is:

| Feature | Usage in This Case Study | Estimated Usage |
| --- | --- | --- |
| Advanced Search | 15 successful calls | 30 credits |
| Advanced Extract | 26 successful URLs | About 10.4 credits |
| Basic Extract | 3 successful URLs | About 0.6 credits |
| **Search and extraction total** | **15 searches + 29 successfully extracted URLs** | **About 41 credits** |

At Tavily's public pay-as-you-go rate of **$0.008 per credit**, the estimated cost is **about $0.328**. This is the estimated credit cost for the recorded usage under the stated paid pricing. Actual costs depend on the number of searches and the amount of content retrieved.

Tavily's extraction costs are estimated in proportion to the number of successful URLs. Actual usage and charges may differ because of per-batch rounding. The free allowances, plan discounts, and caller-side model costs for both services are not included.

### **How to Choose an AnySearch Plan**

After estimating how many calls a complete task requires, you can choose a plan. The following quota and pricing details are based on product information dated November 5, 2026.

| User Needs | AnySearch Plan and Main Rules |
| --- | --- |
| Try common tasks or handle light daily searches | **Free:** 1,000 requests per day, up to 10 QPS. The quota resets daily at 08:00 Beijing time and does not roll over. |
| Need additional quota and want purchased quota to remain valid over time | **Pro:** $3 per 1,000 requests. A one-time prepaid package. Quota can be accumulated and does not expire. Up to 20 QPS. |
| Need dedicated capacity, quota isolation, or custom services | **Enterprise:** Custom pricing based on requirements. 50 QPS by default, adjustable according to the order. Service scope is defined in the contract. |

When choosing a plan, first check whether Free covers your daily usage. Then consider whether you need Pro quota or Enterprise services. All API keys under the same account share the self-service quota. Any remaining Pro quota is used first. Once it is exhausted, the remaining Free quota for that day is used.

> Plan note: All three plans support API, MCP, and Skill. QPS is the request rate limit and does not directly indicate how quickly a research report can be completed.

## **Other Questions to Consider When Choosing a Service**

### **Q1 When Should You Use MCP, and When Should You Use the API Directly?**

Use MCP when you want the Agent to select tools based on the task, adjust parameters, and continue searching for additional information. Use the API directly when you want your application to send requests, process results, and control the workflow itself. For each option, refer to the relevant documentation for details on the tools, parameters, and authentication.

### **Q2 How Should You Handle Research Materials in PDF Format?**

AnySearch's `extract` tool retrieves the content of HTML webpages. If a report is only available as a PDF, you can use a file parsing tool alongside AnySearch. If an official webpage version is available, you can search for and extract its content directly.

### **Q3 Do You Need to Check the Domain Before Every Search?**

For general web searches, you can use `search` directly. When you need to search a specific domain, first use `get_sub_domains` to check the valid parameters, such as product codes for market data or years for industry statistics. This makes it easier to define your query clearly. If the results are insufficient, you can also switch to general web search and read the source content.

### **Q4 Can the Agent Write Conclusions Directly from the Returned Content?**

First, link key findings to their sources and check the dates, units, and status of the information. If the source has not been read, its content is truncated, or the data conflicts with other sources, the answer should state what cannot yet be confirmed before presenting an overall analysis.

For industry research that requires both general web search and specialized information retrieval across multiple domains, you can start with the [AnySearch MCP installation guide](https://www.anysearch.com/docs/mcp-install). Choose one-click installation or the configuration for your client. Try the service anonymously, then test it with a real task from your work to see how well it searches for information and retrieves source content. After registering, you can use the Free plan and choose Pro or Enterprise based on your actual usage.
