firecrawl-toolkit 0.0.10

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.
• Flexible Environment Variable Configuration: Supports fine-tuned service configuration via environment variables.

Available Tools
