AI Docs

An MCP (Model Context Protocol) server that provides indexed, searchable access to Anthropic Claude and Google Gemini documentation.

Features

• Full-text search across both documentation sources with fuzzy matching
• Playwright-powered crawling for JavaScript-rendered pages (Anthropic)
• TTL-based caching with memory and file layers
• 4 MCP tools: search_docs, fetch_page, list_sections, refresh_index

Installation

npm install
npx playwright install chromium
npm run build
