I've been seeing a bunch of posts on this subreddit where people are afraid to start contributing to open source or don't know how to start. To get y'all started, I made a couple of beginner friendly GitHub issues that are "good first issues". They're really easy to do, and I provided step by step instructions. Very simple things like "add an icon". I've been building MCPJam, an open source LLM chat playground for MCP servers. It's a MCP server testing tool, like Postman for MCP servers. You'll learn a lot about building LLM clients, working with React, Hono, Vercel AI SDK, lots of AI product engineering concepts. If you're interested in contributing, or checking out the project, here's the GitHub: https://github.com/MCPJam/inspector To start, you can take a look at the Issues tab and see if there's anything there that interests you.

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: https://github.com/MCPJam/inspector I’m build

ing an active MCP dev community I’m building a MCPJam dev Discord community. We talk about MCPJam, but also share general MCP knowledge and news. Active every day. Please check it out! https://discord.com/invite/Gpv7AmrRc4
In MCPJam: Open-Source Postman for MCP
For the past couple of weeks, I've been building the MCPJam inspector, an open source MCP inspector to test and debug MCP servers. It's a fork of the original inspector, but with design upgrades, and LLM chat. If you check out the repo, please drop a star on GitHub. Means a lot to us and helps gain visibility. I'm so excited to finally launch new features: Multiple active connections to several MCP servers. This will come especially useful for MCP power developers who want to test their server against a real LLM. Upgrade LLM chat models. Choose between a variety of Anthropic models up to Opus 4. Logging upgrades. Now you can see all client logs (and server logs soon) for advanced debugging. Please check out the repo and give it a star: https://github.com/MCPJam/inspector Join our discord! https://discord.gg/A9NcDCAG
