firecrawl-toolkit 0.0.12

A high-performance, asynchronous MCP server for Firecrawl Search, featuring connection pooling, request retries, and intelligent input parsing.

Firecrawl MCP Toolkit

A high-performance, asynchronous MCP server that provides comprehensive Google search and web content scraping capabilities through the Firecrawl API (excluding some rarely used interfaces).

This project is built on httpx, utilizing asynchronous clients and connection pool management to offer LLMs a stable and efficient external information retrieval tool.

Key Features

• Asynchronous Architecture: Fully based on asyncio and httpx, ensuring high throughput and non-blocking I/O operations.
• HTTP Connection Pool: Manages and reuses TCP connections through a global httpx.AsyncClient instance, significantly improving performance under high concurrency.
• Concurrency Control: Built-in global and per-API endpoint concurrency semaphores effectively manage API request rates to prevent exceeding rate limits.
• Automatic Retry Mechanism: Integrated request retry functionality with exponential backoff strategy automatically handles temporary network fluctuations or server errors, enhancing service stability.
• Intelligent Country Code Parsing: Includes a comprehensive country name dictionary supporting inputs in Chinese, English, ISO Alpha-2/3, and other formats, with automatic normalization.
• Response Field Mapping: Search/Scrape responses are normalized into minimal, client-facing JSON schemas instead of upstream passthrough payloads.
• Noise Reduction for Scrape: Built-in excludeTags selector filtering removes common non-content blocks (navigation, ads, sidebars, comments, etc.) to improve signal quality.
• Flexible Environment Variable Configuration: Supports fine-tuned service configuration via environment variables.

• When using multiple services, please specify different lock files for each.

Configure MCP Client

Add the following server configuration in the MCP client configuration file:

{
  "mcpServers": {
    "firecrawl": {
      "command": "python3",
      "args": ["-m", "firecrawl-toolkit"],
      "env": {
        "FIRECRAWL_API_KEY": "<Your Firecrawl API key>"
      }
    }
  }
}

{
  "mcpServers": {
    "firecrawl": {
      "command": "uvx",
      "args": ["firecrawl-toolkit"],
      "env": {
        "FIRECRAWL_API_KEY": "<Your Firecrawl API key>"
      }
    }
  }
}

Tool Parameters and Usage Examples

firecrawl-search: Perform web / news / images search

Parameters:

• query (str, required): Keywords to search.
• country (str, optional): Specify the country/region for search results. Supports Chinese names (e.g., "China"), English names (e.g., "United States"), or ISO codes (e.g., "US"). Default is "US".
• search_num (int, optional): Number of results to return, range 1-100. Default is 20.
• search_time (str, optional): Filter results by time range. Available values: "hour", "day", "week", "month", "year".

Example:

result_json = firecrawl_search(
    query="AI advancements 2024",
    country="United States",
    search_num=5,
    search_time="month"
)

Response (mapped):

• Top-level fields: success, country, data, creditsUsed
• data.web[]: title, description, url
• data.news[]: title, snippet, url, date
• data.images[]: title, imageUrl, url
• web / news / images remain arrays and may be empty ([])
• Missing mapped fields are preserved as null
• Output is compact single-line JSON (no extra spaces)

Example response:

{"success":true,"country":"US","data":{"web":[{"title":"Example Web","description":"Example description","url":"https://example.com"}],"news":[],"images":[{"title":"Example Image","imageUrl":"https://img.example.com/1.jpg","url":"https://example.com/image"}]},"creditsUsed":3}

firecrawl-scrape: Scrape webpage content

Parameters:

• url (str, required): URL of the target webpage.

Example:

result_json = firecrawl_scrape(
    url="https://www.example.com"
)

Built-in noise filtering:

• The tool uses an internal excludeTags selector set to suppress noisy DOM regions and prioritize main content quality.

Response (mapped):

• Top-level fields: success, proxyUsed, title, description, language, markdown, creditsUsed
• markdown is URL-decoded before returning to the client
• Missing mapped fields are preserved as null
• Output is compact single-line JSON (no extra spaces)

Example response:

{"success":true,"proxyUsed":"auto","title":"Example Page","description":"Example summary","language":"en","markdown":"Hello world!","creditsUsed":1}

Response Contract Notes

• firecrawl-search and firecrawl-scrape success payloads are mapped to stable minimal schemas.
• Missing mapped fields are preserved as null (arrays remain arrays, and may be empty).
• Both success and error responses are compact single-line JSON.
• This is a breaking response-contract change for consumers that relied on the old full passthrough structure (query_details + results).
