Overview

What is MCP Gateway?

MCP Gateway (Unla) is a lightweight, highly available gateway service written in Go that allows individuals and organizations to convert existing MCP Servers and APIs into MCP Protocol–compliant endpoints through configuration only, with zero code changes. It is platform-agnostic and supports bare metal, VMs, ECS, and Kubernetes deployments.

How to use MCP Gateway?

Deploy with Docker using environment variables (secret key, admin credentials), then access the built-in web UI at port 8080 to add MCP Server configurations via YAML. After setup, use the exposed SSE or Streamable HTTP endpoints (port 5235) to connect your MCP client.

Key features of MCP Gateway

  • Convert RESTful APIs to MCP Servers via YAML configuration
  • Proxy existing MCP services without code changes
  • Support for MCP SSE and Streamable HTTP transports
  • Built-in management UI for configuration and monitoring
  • Multi-tenant support with persistent, recoverable sessions
  • OAuth-based pre-authentication for MCP Servers
  • Hot-reloading configuration from disk, SQLite, PostgreSQL, or MySQL

Use cases of MCP Gateway

  • Transform legacy REST APIs into MCP-compliant endpoints
  • Aggregate multiple MCP servers behind a single gateway
  • Enable multi-tenant access to MCP resources
  • Deploy MCP infrastructure without modifying existing code
