MCP Spine v0.2.5: I Built a Full Middleware Stack for MCP Tool Calls

Last month I shipped MCP Spine v0.1 - a basic proxy that sat between Claude Desktop and MCP servers. It did schema minification and security basics. Since then, it's grown into a full middleware stack. Here's everything in v0.2.5 and why each piece exists. The Starting Point 57 tools. 5 servers. Claude Desktop config file with one entry pointing to Spine. Everything routes through the proxy. pip install mcp-spine mcp-spine init The setup wizard detects your installed servers (npx, node, Python), asks what features you want, and writes a tailored config.
