What does the add-mcp-package skill do?

It automates the creation of a new MCP workspace package, generating all necessary files like pyproject.toml, tools.py, and server.py while wiring them into the root project.

Is this skill specific to a certain language?

Yes, it is designed for Python-based environments using the FastMCP framework and the uv package manager.

Does it support standalone testing?

Absolutely. The skill generates a server.py file that allows you to run the new MCP package in isolation using either HTTP or stdio transports.

Can I use this for non-Riksarkivet projects?

While it follows the ra-mcp naming conventions and structure, the underlying patterns for FastMCP and workspace management are applicable to many Python-based MCP projects.

API Development

Scaffolds standardized Model Context Protocol (MCP) workspace packages including directory structure, configuration, and tool registration.

The add-mcp-package skill automates the creation of new MCP servers within a workspace, ensuring consistent architecture and best practices. It generates a complete boilerplate including pyproject.toml, FastMCP tool definitions, standalone server entry points, and test files. By handling the complex wiring required to integrate new modules into a root server, this skill enables developers to focus on tool logic rather than infrastructure setup, specifically optimized for the Riksarkivet ra-mcp ecosystem.
