Kong Gateway is a cloud-native, scalable API gateway that manages API, AI LLM, and Model Context Protocol (MCP) traffic with advanced security, observability, and extensibility features.
sxhxliang/mcp-access-point
MCP Access Point is a protocol conversion gateway written in Rust that bridges traditional HTTP services and Model Context Protocol clients. It lets MCP clients call existing REST APIs directly, with no server-side interface modifications. The gateway is built on Pingora, the high performance proxy library Cloudflare uses for its own edge traffic. Configuration is driven by a YAML file. The mcps section lists MCP services, each with a unique id, an associated upstream id, and a path to an OpenAPI specification that may be a local JSON or YAML file or a remote HTTP or HTTPS URL. The upstreams section defines backend nodes with weights, a load balancing algorithm (roundrobin, random or ip_hash), the upstream scheme, Host header handling, and extra headers such as API keys or bearer tokens. Routes can also be declared by hand with an operation_id, a URI template, an HTTP method and an optional input schema for validation, so a single backend endpoint becomes a named MCP tool. Two transports are supported: Streamable HTTP (2025-03-26) at ip:port/mcp and SSE (2024-11-05) at ip:port/sse. Multi-tenancy is built in. Every configured service is reachable individually at /api/{service_id}/mcp or /api/{service_id}/sse, while the root paths expose all services at once and the gateway routes each request to the matching backend. A REST admin API and an admin dashboard allow configuration updates at runtime without restarting the service. The README reports interoperability with MCP Inspector, Cursor Desktop, Windsurf, VS Code and Trae. Installation is from source, running cargo run with a config file argument. The project suits teams that already operate HTTP APIs and want to expose them to MCP capable assistants and IDEs behind one proxy, including cases where the client needs SSE but the backend does not speak it.
