DocsScraper MCP Server

An MCP server that connects to the DocsScraper web API to provide semantic search capabilities through documentation chunks.

Features

• Semantic Search: Search through documentation chunks using embeddings and AI validation
• API Integration: Connects to your DocsScraper web application via REST API
• Fallback Sources: Automatically falls back to scraper sources when no local results are found
• Configurable Results: Control the number of search results (1-10, default: 5)
• Service Filtering: Filter search results by specific service names (case-insensitive)

Configuration

The server requires the following environment variables:

• DOCS_SCRAPER_API_KEY: API key for authentication (required)

Tools

search_docs

Parameters:

• query (string, required): The search query to find relevant documentation
• top (number, optional): Maximum number of results to return (1-10, default: 5)
