# Hermes Agent

> Use Darwin as an MCP capability layer for Hermes Agent.

Add Darwin to `~/.hermes/config.yaml`:

```yaml theme={null}
mcp_servers:
  darwin:
    url: "https://mcp.darwin.so/mcp"
    auth: oauth
    trust: untrusted
```

Run `/reload-mcp`, complete OAuth, and verify the current tools. The `untrusted` setting keeps write-capable tools behind Hermes approval.

```text theme={null}
Search Darwin for a harmless capability. Show the exact capability ID and
revision, and stop before starting an Action.
```

After a timeout or restart, recover the stored `actionId` with `get_action` rather than starting duplicate work.
