Expo Docs MCP Server

# Expo Docs MCP Project Overview ## Purpose This is an MCP (Model Context Protocol) server for semantic search of pre-indexed Expo documentation. It provides intelligent search capabilities over Expo SDK documentation using vector embeddings. ## Tech Stack - **Language**: TypeScript - **Runtime**: Node.js - **Key Dependencies**: - `@modelcontextprotocol/sdk` - MCP server framework - `@langchain/openai` - OpenAI embeddings - `@langchain/textsplitters` - Token-based text chunking - `@langchain/community` - Vector stores (HNSWLib) - `mdx-to-md` - MDX to Markdown conversion ## Architecture - **MCP Server** (`src/mcp-server.ts`) - Main server handling search requests - **Services Directory** (`src/services/`) - Core functionality: - `semantic-search.ts` - Vector-based document search - `vectorizer.ts` - Document chunking and embedding - `mdx-compiler.ts` - MDX to Markdown conversion - `version-manager.ts` - Multi-version documentation handling - `local-repo-reader.ts` - Local Expo repo file reading ## Current Issue Working on fixing MDX to Markdown conversion that's corrupting code blocks. The goal is to preserve complete TypeScript/JavaScript code examples during conversion from Expo's MDX files to searchable markdown.
