About Hackage Documentation MCP

What is Hackage Documentation MCP: Real-Time Docs, Seamless Integration?

Designed as a Machine-Controlled Program (MCP), this tool establishes a conduit between AI assistants and Hackage's repository of Haskell documentation. By enabling real-time access to authoritative module specifications and library details, it mitigates the cognitive limitations of AI models trained on sparse Haskell datasets. The system ensures developers and AI collaborators alike can retrieve precise, version-specific documentation to bolster code accuracy and conceptual clarity.

How to Use Hackage Documentation MCP: Real-Time Docs, Seamless Integration?

Initialization requires installing Python 3.7+ and dependencies via pip install httpx beautifulsoup4 fastmcp. Launch the MCP server with python main.py, then invoke the get_docs API endpoint. Specify package names, versions, and modules to fetch meticulously parsed documentation. For instance, querying get_docs("lens", "5.0.0", "Control.Lens") delivers up-to-the-minute details on type signatures and module hierarchies.

Hackage Documentation MCP FAQ

FAQ About Hackage Documentation MCP: Real-Time Docs, Seamless Integration

Does this require active internet access? Yes, the system fetches real-time data from Hackage's servers. Offline caching mechanisms are under development.

How does version handling work? Explicit version parameters ensure reproducible documentation retrieval, with automatic fallback to latest stable releases when unspecified.

Can it parse deprecated modules? Yes, though deprecated status is flagged prominently in returned metadata to aid contextual awareness.

Hackage Documentation MCP

Overview

This Machine-Controlled Program (MCP) provides an interface for AI assistants to access Haskell documentation from Hackage. It allows AI models to retrieve precise, up-to-date documentation for specific Haskell modules, improving the AI's ability to assist with Haskell programming despite limited training data in this domain.

Problem Statement

AI language models often have insufficient training data on Haskell compared to more mainstream programming languages. This results in:

Less accurate code generation for Haskell
Difficulty understanding Haskell's unique features and abstractions
Inaccurate or outdated information about Haskell libraries and modules

This tool bridges that gap by enabling AI to retrieve authoritative documentation from Hackage in real-time.

Features

Retrieve documentation for specific modules from any package on Hackage
Specify exact package versions to ensure accuracy
Clean, text-based output that's easily consumable by AI assistants

Installation

Ensure you have Python 3.7+ installed
Install the required dependencies:

pip install httpx beautifulsoup4 fastmcp

Usage

You can use this MCP with any AI assistant that supports the MCP protocol.

Running the Server

python main.py

This will start the MCP server using stdio transport.

API

The MCP exposes the following tool:

`get_docs(package, version, module)`

Retrieves documentation for a specific Haskell module.

Parameters:

package (string): The Hackage package name (e.g., "lens", "yesod-persistent")
version (string): The package version (e.g., "5.0.0", "2.10.0")
module (string): The module name to look up (e.g., "Control.Lens", "Database.Persist")

Returns:

The extracted documentation text for the specified module, or an error message if retrieval fails

Examples:

# Get documentation for Control.Lens from lens 5.0.0
get_docs("lens", "5.0.0", "Control.Lens")

# Get documentation for Data.Vector.Algorithms from vector-algorithms 0.8.0
get_docs("vector-algorithms", "0.8.0", "Data.Vector.Algorithms")

Use Cases

Learning Haskell libraries : Get detailed information about specific modules while working with the AI
Understanding type signatures : Access accurate type information for functions in Haskell modules
Exploring module hierarchies : Understand how modules are organized within Haskell packages
Verifying AI-generated code : Compare AI suggestions with official documentation

Benefits

Provides AI with access to accurate, up-to-date Haskell documentation
Improves the quality of AI-generated Haskell code
Enhances the AI's ability to explain Haskell concepts with authoritative references
Reduces hallucinations when discussing Haskell libraries

Limitations

Requires an internet connection to access Hackage
Only provides documentation content, not the implementation code
Documentation quality varies between Haskell packages

Contributing

Contributions to improve this tool are welcome! Some potential areas for enhancement:

Adding support for downloading and parsing package source code
Implementing caching to reduce network requests
Expanding to support other Haskell documentation sources
