**One interface. Many connections. Manifold.** English | [日本語](README.ja.md) Manifold is a gateway that acts as an MCP server while connecting to multiple external MCP servers and OpenAPI / Swagger-compliant REST APIs on the backend. The name **Manifold** comes from an engine's **intake manifold**. An intake manifold is the component that distributes air and fuel evenly and efficiently from a single inlet to multiple cylinders. We named this project **Manifold** because its structure is similar.
