Pacman

Pacman MCP Server provides a focused interface for querying and retrieving package and container information from major package indices and registries. It enables end users and large language model clients to search PyPI, npm, crates.io, Docker Hub, and Terraform Registry, as well as Docker images and Terraform modules, through a consistent MCP endpoint.

How to use

You interact with Pacman MCP Server through an MCP client to search for packages, get detailed package information, search Docker images, and fetch Terraform module data. Use the server to quickly locate packages and obtain metadata you can present to users or use to drive automated workflows. Focus on practical queries like finding a package by name, listing top results, or retrieving version details for a specific package.

How to install

Prerequisites vary by install method. Choose the method that best fits your environment.

pip install mcp-server-pacman

After installation, run the server with:

python -m mcp_server_pacman

To run Pacman MCP Server using uvx (recommended for direct MCP integration):

uvx

Then run the specific MCP server command shown below when prompted by your MCP client integration workflow.

If you prefer Docker, pull and run the image directly:
```docker pull oborchers/mcp-server-pacman:latest````docker run -i --rm oborchers/mcp-server-pacman:latest```

## Configuration

Configure Pacman MCP Server for your MCP client by providing one or more runtime configurations. The following configurations are shown in typical setups to integrate Pacman with clients like Claude.app and VS Code.

"mcpServers": { "pacman": { "command": "uvx", "args": ["mcp-server-pacman"] } }

## Advanced configuration for clients

For Claude.app using uvx, you add a dedicated MCP server entry that points the client to run the Pacman server via uvx. For Docker usage, you provide a server entry that runs the Docker image. For Python (pip) installation, you provide a Python execution entry that runs the module as a script.

"mcpServers": { "pacman": { "command": "uvx", "args": ["mcp-server-pacman"] } }

## Customization

You can customize the user agent string used by the server by supplying a --user-agent argument in the start command. This is useful for analytics and identifying your deployment.

## Development and testing

Run the test suite and formatting checks to ensure stability during development. Use the provided commands to execute tests, style checks, and format code.
