ra-mcp: RA-MCP is a Model Context Protocol (MCP) server and CLI tool designed for searching and browsing millions of AI-transcribed historical documents from the Swedish National Archives. It enables full-text search, interactive document viewing, and provides archival research guides, all accessible via MCP-compatible LLM clients or its dedicated command-line interface.; action_mcp: ActionMCP is a Ruby gem that simplifies the integration of Ruby on Rails applications with the Model Context Protocol (MCP), acting as an MCP server. It enables AI assistants to interact with external data sources and tools in a standardized, secure, and production-ready manner.
