Open-Source Postman for MCP

What it does

Test and debug MCP servers with a desktop GUI that actually works with stdio transport — because let's be honest, most MCP servers aren't HTTP. Open Source Postman for MCP solves this. Connect to any MCP server (stdio, HTTP, or SSE), explore its tools with auto-generated forms, execute requests with one click, and save everything to history. git clone https://github.com/baristaGeek/open-source-postman-for-mcp cd open-source-postman-for-mcp npm install npm run dev Usage Connect to a stdio server Most MCP servers use stdio transport (like the official filesystem server): # Required for AI features (auto-select, summarization) ANTHROPIC_API_KEY=sk-ant-... # Required for credential encryption…from github.com
