# MCP server

> Connect assistants to Veridical verification tools

Start the bundled stdio server:

```bash theme={null}
veridical-engine mcp-server
```

The server supports:

* `veridical_verify` and `veridical_verify_staged`;
* `veridical_review_pr` and `veridical_request_fix`;
* `veridical_system_map` and `veridical_explain`;
* `veridical_onboard` and `veridical_probe`;
* `veridical_ratchet` and `veridical_residual_gate`.

Configure the client to launch the exact signed sidecar shipped with the CLI or
extension. MCP tool output preserves structured verdicts and receipts. The
client remains responsible for permission prompts and for preventing an
assistant from turning an advisory verdict into an unauthorized merge.
