mcp_mediator

Overview

The MCP Mediator is a Java implementation that bridges existing code and services with the Model Context Protocol. It aggregates various components into a unified MCP server, eliminating the need for manual maintenance of multiple servers. The framework supports both tool generation from existing code and proxying multiple MCP servers, with extensible request handling and support for different transport mechanisms including stdio and sse.

FAQ

How do I convert existing Java code to MCP tools?

Use the @McpService and @McpTool annotations on your classes and methods. Then register the service with the DefaultMcpMediator using McpServiceFactory.create().

Can this work with existing Spring Boot applications?

Yes, there's a Spring Boot starter module (mcp-mediator-spring-boot-starter) that provides autoconfiguration to generate MCP servers automatically for available endpoints.

What transport mechanisms are supported?

Currently supports stdio and SSE transport mechanisms. Additional transport methods are planned for future releases.
