Building a rules-file MCP server in 2026
A developer has created a tool called FastMCP to streamline the generation of assistant rules files across multiple AI platforms. This tool allows a single prompt to create synchronized instruction files for Claude, Cursor, and Copilot, eliminating the need for manual copy-pasting and reducing the risk of inconsistent configurations. The FastMCP server operates locally, communicating with assistants via standard input/output, with authentication handled through file system permissions rather than API keys. The developer also offers a browser-based version of the rules-file generator for simpler, one-off use cases. AI
