Documentation Hunter

Search-Driven Documentation Discovery | Apify MCP Compatible

This actor takes a search query as input, uses Google Search to find relevant documentation, and then crawls the top results to extract their content. Perfect for finding specific documentation, tutorials, or guides on any topic. Ideally to be used to feed into coding AI assistants for up-to-date documentation.

How It Works

1. Search: Uses apify/google-search-scraper to find relevant documentation based on your query
2. Filter: Optionally filters out unwanted domains
3. Crawl: Uses apify/website-content-crawler to extract clean content from the top results
4. Return: Provides structured documentation data ready for consumption

Key Features

• 🔍 Google-Powered Search: Leverages Google's search algorithm to find the most relevant documentation
• 🤖 Actor Composition: Uses proven Apify actors for search and crawling
• 🎯 Targeted Results: Configurable number of results (1-10)
• 🚫 Domain Filtering: Exclude unwanted domains from results
• 📄 Clean Content: Extracts readable content using readability mode
• 🔗 MCP Compatible: Works seamlessly with Apify MCP Server

Technology Stack

• Language: TypeScript with full type safety
• Framework: Apify SDK
• Search: Google Search Scraper (apify/google-search-scraper)
• Crawling: Website Content Crawler (apify/website-content-crawler)

Apify MCP Compatibility

This actor is fully compatible with Apify MCP (Model Context Protocol) without requiring any custom MCP server implementation. The actor works seamlessly with the official Apify MCP Server.

How Apify MCP Works

The Apify MCP Server automatically discovers Apify actors and exposes them as MCP tools/resources. Here's how it works:

1. Actor Discovery: The MCP server scans the Apify Store and discovers available actors
2. Schema Mapping: Each actor's input schema is automatically converted to MCP tool parameters
3. Tool Creation: Actors become callable tools that AI assistants can use
4. Result Handling: Actor outputs are returned as MCP resources

Key Benefits

• 🤖 AI Integration: Use Documentation Hunter directly from Windsurf, Cursor, Claude, and other MCP-compatible tools
• 🔧 No Custom Code: No need to implement MCP server functionality in the actor
• 📊 Automatic Discovery: The actor is automatically available as an MCP tool
• 🎯 Schema-Driven: Input parameters are automatically mapped from the input schema
• 🚀 Production Ready: Works with the official Apify MCP infrastructure

Apify MCP Server

The Documentation Hunter actor is exposed as a tool through:

• Hosted Server: https://mcp.apify.com
• Local CLI: npx @apify/actors-mcp-server
• Actor Name: Available as a tool based on the actor's input schema
