# ContextMCP

**Self-hosted MCP server for your documentation.** Index your documentation from across the sources and serve it via the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) and REST API.

## Quick Start

```bash
# Scaffold a new project
npx contextmcp init my-docs-mcp

# Follow the prompts, then:
cd my-docs-mcp
npm install

# Configure your API keys
cp .env.example .env
# Edit .env with your PINECONE_API_KEY and an embedding provider key
# (OPENAI_API_KEY for provider: openai, or GEMINI_API_KEY for provider: gemini)

# Configure your documentation sources
# Edit config.yaml

# Index your documentation
npm run reindex

# Edit the cloudflare-worker
# Deploy the MCP server
cd cloudflare-worker
npm install
npm run deploy
```

## What is ContextMCP?

ContextMCP creates a searchable knowledge base from your documentation that AI assistants can query via the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/).

### Supported Content Types

| Parser     | Content Types         | Examples                       |
| ---------- | --------------------- | ------------------------------ |
| `mdx`      | MDX/JSX documentation | Mintlify, Fumadocs, Docusaurus |
| `markdown` | Plain Markdown files  | READMEs, CHANGELOGs            |
| `openapi`  | OpenAPI/Swagger specs | API reference docs             |

### How It Works

1. **Parse** - Extract content from your docs, APIs, and READMEs
2. **Chunk** - Split into semantic chunks optimized for search
3. **Embed** - Generate embeddings using OpenAI or Gemini
4. **Store** - Upload to Pinecone vector database
5. **Search** - Query via MCP from AI assistants

## Ecosystem

### Add a chat UI with ContextChat

ContextMCP serves retrieval; pair it with [**ContextChat**](https://github.com/dodopayments/context-chat) to give your docs a drop-in, embeddable "Ask AI" widget. ContextChat is a single Cloudflare Worker that queries your ContextMCP `/search` endpoint and streams answers with inline citations — add it to any site or docs page with one `<script>` tag.
