Overview

MCP Partner is a web-based tool that provides an interface to test and interact with Model Context Protocol (MCP) servers. It supports both SSE (Server-Sent Events) and Streamable HTTP connections, making it compatible with various MCP server implementations. The tool features automatic tool discovery, interactive testing with form-based and JSON modes, request logging, and configuration management. It also solves CORS issues through built-in proxy functionality.

Try asking AI

After installing, here are 5 things you can ask your AI assistant:

you:Debugging MCP server tool implementations during development
you:Testing MCP server capabilities before integration with client applications
you:Demonstrating MCP functionality to team members or clients
you:How do I handle CORS issues with local MCP servers?
you:Can I use this tool with my existing MCP server?

When to choose this

Choose MCP Partner when you need a quick, no-install web tool to test MCP servers during development or demonstrations, especially when you need to visualize tool interactions and request/response flows.

When NOT to choose this

Don't choose MCP Partner if you need a persistent client with authentication management, comprehensive request history across sessions, or if you're working with strictly internal networks that block external proxy services.

FAQ

How do I handle CORS issues with local MCP servers?
MCP Partner provides three proxy solutions: 1) Vercel deployment with built-in CORS proxy, 2) Use a public proxy service like corsproxy.io, 3) Run Pancors locally as a proxy.
Can I use this tool with my existing MCP server?
Yes, as long as your MCP server supports SSE or Streamable HTTP protocols. The tool will automatically discover and list available tools on your server.
