## MCP tools (2)

### `check_stub` (~84 tokens)

Check a Stub receipt

Verify what an AI agent did on someone's behalf, and whose side it was on. Takes a stub id and returns the signed record: what was asked, what was done, what money moved, and what commercial influence the operator disclosed. Resolves at a neutral registry, not on the agent's own servers.

Input parameters:

- `stub_id` (string, required): the 64 character stub id

### `get_witness_key` (~33 tokens)

Get the registry witness key

Return the registry's public witness key, so countersignatures on checks can be verified independently without trusting the registry.
