FlowMCP MCP Server

What is FlowMCP?

FlowMCP is a framework that adapts existing web APIs (e.g., REST) into a standardized Model Context Protocol (MCP) interface, enabling AI systems to consume those APIs in a structured, testable, and semantically consistent way. It abstracts complex APIs into AI-friendly schema definitions and provides built-in tools for testing, validation, and pre/post processing.

How to use FlowMCP?

Install the package, create a schema (.mjs file) following the documented structure, then activate it using FlowMCP.activateServerTools({ server, schema, serverParams }) in a Node.js script that creates an MCP server with StdioServerTransport. Environment variables (e.g., API keys) are passed via serverParams. Pre-built schemas are available in the community repository.
