What is MCP Simple Gateway?
MCP Simple Gateway is a proxy server designed to aggregate and manage multiple Model Context Protocol (MCP) servers. It acts as a single point of entry, simplifying access and management of various MCP services.
How to use MCP Simple Gateway?
The gateway can be run via CLI using npx mcp-simple-gateway --config config.json or via Docker Compose. Configuration is done through a JSON file (config.json) where you define proxy server options and individual MCP server configurations, including command execution or URL endpoints. Access individual MCP servers through the gateway's address and specified paths, e.g., http://localhost:3000/time/sse.

FAQ from MCP Simple Gateway
What is the purpose of the authTokens in the configuration?
What is the purpose of the authTokens in the configuration?
The authTokens are used for authentication. The tokens defined in proxyServer.options.authTokens are used as default for all servers. You can override them for specific servers using mcpServers.[serverName].proxyOptions.authTokens.
How do I configure the gateway to forward requests to a StreamableHTTP MCP server?
How do I configure the gateway to forward requests to a StreamableHTTP MCP server?
You need to define the server in the mcpServers section with the type set to streamableHttp and specify the url of the server.
Can I use different authentication tokens for different MCP servers?
Can I use different authentication tokens for different MCP servers?
Yes, you can override the default authentication tokens for specific servers by defining the authTokens array within the proxyOptions of the server's configuration.
What are the supported logging levels?
What are the supported logging levels?
The supported logging levels are: debug, info, warn, and error. You can configure the logging level using the logLevel parameter in the proxyServer.options section.
How do I access a specific MCP server through the gateway?
How do I access a specific MCP server through the gateway?
The URLs for accessing MCP servers will be based on the gateway address and the server name defined in the mcpServers configuration, e.g., http://localhost:3000/time/sse.
