Consolidate unlimited Model Context Protocol servers and REST APIs behind a single lightweight meta-interface to prevent context window flooding.

MCP Gateway is a high-performance Rust proxy that bridges AI clients like Claude, Cursor, and Codex with extensive catalogs of MCP servers and REST APIs. By replacing dozens or hundreds of individual tool definitions with a compact meta-surface of meta-tools, it allows agents to discover and invoke capabilities on demand without consuming massive upfront token context. Designed for reliability and enterprise environments, it features sub-second hot-reloads, tool-poisoning protection, multitenant identity forwarding, automated client setup wizards, and built-in resilience primitives like circuit breakers and retries.

Key Features

01Production resilience controls including circuit breakers, automatic retries with backoff, and rate limiting
02Zero-downtime hot-reloading of backend configurations and toolchains in under 10ms
03One-command migration wizard that scans and imports existing configurations across popular AI clients
04Dynamic on-demand tool discovery and invocation via a compact meta-surface
05Built-in support for 110+ REST capabilities and easy OpenAPI specification imports
0685 GitHub stars

Use Cases

01Exposing private or public REST APIs directly to LLM agents as native tools via OpenAPI imports
02Connecting dozens of development and workspace MCP servers to AI coding assistants without exceeding prompt context budgets
03Enforcing security policies, prompt injection scanning, and multitenant identity verification across disparate agent tools
