Express

About

Express enables seamless integration of your existing Express.js application endpoints as structured tools consumable by Model Context Protocol (MCP) clients, such as AI development environments and agents. It offers zero-configuration setup, preserving OpenAPI v3 and Zod schemas, and respecting existing Express authentication middleware. Supporting both in-process mounting within your Express app and standalone gateway deployments, Express handles various streaming protocols including Server-Sent Events (SSE), NDJSON, and HTTP chunked streaming, making your Express services readily available for powerful AI-driven interactions.
