FastMCP

Build MCP servers in Python with FastMCP, validate them locally, install them into MCP clients, and deploy them as HTTP endpoints.

When to Use

Use this skill when the task is to:

• create a new MCP server in Python
• wrap an API, database, CLI, or file-processing workflow as MCP tools
• expose resources or prompts in addition to tools
• smoke-test a server with the FastMCP CLI before wiring it into Hermes or another client
• install a server into Claude Code, Claude Desktop, Cursor, or a similar MCP client
• prepare a FastMCP server repo for HTTP deployment

Use native-mcp when the server already exists and only needs to be connected to Hermes. Use mcporter when the goal is ad-hoc CLI access to an existing MCP server instead of building one.
