# Package Documentation MCP Server

An MCP (Model Context Protocol) server that provides LLMs with efficient access to package documentation across multiple programming languages.

## Features

- **Multi-Language Support**:
  - Go packages via `go doc`
  - Python libraries via built-in `help()`
  - NPM packages via registry documentation

- **Smart Documentation Parsing**:
  - Structured output with description, usage, and examples
  - Focused information to avoid context overload
  - Support for specific symbol/function lookups

- **Performance Optimised**:
  - Built-in caching
  - Efficient parsing
  - Minimal memory footprint

## Installation

```bash
npx -y mcp-package-docs
```

## Usage

### As an MCP Server

1. Add to your MCP settings configuration:

```json
{
  "mcpServers": {
    "package-docs": {
      "command": "npx",
      "args": ["-y", "mcp-package-docs"]
    }
  }
}
```

2. The server provides three tools:

#### lookup_go_doc

Fetches Go package documentation
```typescript
{
  "name": "lookup_go_doc",
  "arguments": {
    "package": "encoding/json", // required
    "symbol": "Marshal"        // optional
  }
}
```

#### lookup_python_doc

Fetches Python package documentation
```typescript
{
  "name": "lookup_python_doc",
  "arguments": {
    "package": "requests",    // required
    "symbol": "get"          // optional
  }
}
```

#### lookup_npm_doc

Fetches NPM package documentation
```typescript
{
  "name": "lookup_npm_doc",
  "arguments": {
    "package": "axios",      // required
    "version": "1.6.0"       // optional
  }
}
```

### Example Usage in an LLM

```typescript
const result = await use_mcp_tool({
  server_name: "package-docs",
  tool_name: "lookup_python_doc",
  arguments: {
    package: "requests",
    symbol: "post"
  }
});
```
