Simplifying client configuration by exposing one endpoint

常见问题

What types of MCP servers are supported?

The gateway supports stdio, SSE, and StreamableHTTP MCP servers.

How do I configure authentication?

Provide an array of authentication tokens in the `proxyServer.options.authTokens` field. These tokens apply to all servers by default, and can be overridden per server via `proxyOptions.authTokens`.

Can I run MCP Simple Gateway with Docker?

Yes, a Docker Compose example is provided in the README, using the image `ghcr.io/denwakeup/mcp-simple-gateway:latest`.

What is the default port?

The default proxy server address and port is `localhost:3000`.

How do I set up CORS?

CORS configuration is optional; you can set `proxyServer.options.cors` using Express.js CORS middleware options.
