DocsetMCP MCP Server

Provides offline Dash docset search via MCP with fast local access and drilldown guidance.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "codybrom-docsetmcp": {
      "command": "uvx",
      "args": [
        "docsetmcp"
      ],
      "env": {
        "DOCSET_PATH": "YOUR_DOCSET_PATH",
        "CHEATSHEET_PATH": "YOUR_CHEATSHEET_PATH"
      }
    }
  }
}

DocsetMCP is an MCP server that lets you search and access your local Dash docsets from AI assistants, providing offline, fast, and precise documentation results without leaving the chat. It ties together your Dash docsets with your MCP client so you can quickly look up APIs, commands, and frameworks while you’re coding or exploring concepts.

How to use

You connect DocsetMCP to your MCP client and start querying your local Dash docsets directly from the conversation. Use natural language prompts to search across installed docsets, filter by language, and drill down into frameworks and members. You can also explore related cheatsheets and commands with quick access and smart ranking that favors exact and prefix matches.

How to install

Prerequisites and options are available depending on your setup.

# Prerequisites
- macOS with Dash installed and desired docsets downloaded
- Python 3.10 or higher
- UV package manager (How to Install)
- An MCP client that supports MCP (Claude Desktop, Claude Code CLI, Cursor IDE, etc.)

# No installation required if your MCP client supports uvx
# Use the following configuration in your MCP client
{
  "mcpServers": {
    "docsetmcp": {
      "command": "uvx",
      "args": ["docsetmcp"]
    }
  }
}
```

```
# Manual installation
pip install docsetmcp

# Then use the same runtime command in your configuration

Configuration

You can customize where DocsetMCP looks for docsets and cheatsheets. By default it searches Dash’s standard directories for DocSets and Cheat Sheets, but you can override these locations with environment variables or command line arguments.

# Environment variables to override locations
export DOCSET_PATH="/path/to/your/docsets"
export CHEATSHEET_PATH="/path/to/your/cheatsheets"

# Run with custom paths
docsetmcp

Usage examples

Once configured, your MCP client can perform searches like: Look up a function in a specific docset, find a class, or list available docsets by language. Use exact names when possible to improve precision.

Troubleshooting

If you run into issues, check your MCP connection, ensure the docset paths are correct, and verify Python version is 3.10 or newer. Common problems include missing docsets in Dash, incorrect command in your MCP config, or environment variable misconfigurations.

Development and testing

Development steps and tests are available for contributors who want to add docsets or improve the server. Run the test suite and development commands as described in the project’s guidelines to validate configurations and docset structures.

Notes on capabilities

DocsetMCP provides multi-docset search, language filtering, name-based matching, smart ranking, and container guidance for frameworks and classes. It supports quick cheatsheet access and direct database querying for fast results, with in-memory caching to speed up repeated queries.
