  • MCPJam: Open-Source Postman for MCP
    1 project | news.ycombinator.com | 30 Jun 2025
    Hey y’all, my name is Matt. I maintain the MCPJam inspector, open source Postman for MCP servers. It’s a fork of the original inspector with upgrades like LLM playground, multi-connection, and better design.

    If you check out the repo, please drop a star on GitHub. We’re also building an active MCP dev community on GitHub.

    New features

    Ollama support in the LLM playground. Now you can test your MCP server against local models like Deepseek, Mistral, Llama, and many more. No more having to pay for tokens for testing.

    Chat with all servers. LLM playground defaults to accepting all tools. You can select / deselect the tools you want fed to the LLM, just like how Claude’s tool selection works.

    Smoother / clearer server connection flow.

    Please consider checking out and starring our open source repo:
