ProxyPI

What it is

Self-healing API proxy MCP for Cursor, Claude Code, or any MCP-compatible client. Send any REST request — if it fails, ProxyPI reads the error, diagnoses the problem using Claude, patches the request, and retries. Successful fixes are remembered and applied instantly next time, without calling Claude.

How it works

You: proxypi_request → POST https://api.example.com/users

ProxyPI:  try → fail → diagnose (Claude) → patch → retry → remember

Next time the same error occurs on the same host and path, the fix is applied from memory instantly — no Claude call needed.

Demo

npx proxypi

Install

npx proxypi

Config

Add to .cursor/mcp.json (project root or ~/.cursor/mcp.json):

{
  "mcpServers": {
    "proxypi": {
      "command": "npx",
      "args": ["-y", "proxypi"],
      "env": {
        "ANTHROPIC_API_KEY": "your-api-key-here"
      }
    }
  }
}

Restart Cursor. Four tools: proxypi_request, proxypi_history, proxypi_replay, proxypi_clear.
