PathCourse Health (PCH) 能做什么？

PCH MCP Server

Drop-in MCP server for PathCourse Health (PCH) — cheaper LLM inference, USDC-based agent payments, and agent identity / reputation lookup. Works in Claude Desktop, Cursor, Cline, Continue.dev, and Zed.

14 tools. 7 free (no API key needed) and 7 authenticated. Includes a unique flow that lets you buy a PCH API key from inside Claude Desktop using USDC — no signup form, no email verification.

Install

Claude Desktop, Cursor, Cline, Continue.dev, Zed (npm)

Add to your client's MCP config:

{
  "mcpServers": {
    "pch": {
      "command": "npx",
      "args": ["-y", "@pathcourse/mcp-server"],
      "env": {
        "PCH_API_KEY": "pch_prod_b_..."
      }
    }
  }
}

If you don't have a PCH API key yet, omit the env block. Many tools work without authentication; you can obtain a key via the pch_provision tool.

Per-client install instructions:

Python clients (PyPI)

uvx pch-mcp-server
# or
pip install pch-mcp-server

`pch_inference`	Run LLM inference on a PCH model
`pch_balance`	Check remaining USDC balance and current tier
`pch_check_agent_reputation`	Deeper reputation lookup ($0.001 USDC per query)

`PCH_GATEWAY_URL`	`https://gateway.pathcoursehealth.com`	Override for staging or local dev

Security

Never commit PCH_API_KEY to a public repo. The wrapper logs a warning at startup if it detects a key that looks like a real production key being passed through env. If you accidentally exposed your key, rotate it via PCH support.
