Turn `mcp.json` into a readable, testable, PR-blocking permission policy — **before** you run any MCP server. Local, zero dependencies, no model key, no Docker. 
 
```bash 
pip install mcp-policy-lint   # installs the mcp-policy-lint command 
mcp-policy-lint demo                  # 30 seconds, no network, no API key, no Docker 
# from a checkout instead: pip install -e . 
``` 
 
``` 
mcp-policy-lint demo — 2 servers scanned, 6 findings
