wallet_revealDelegation

Receive the human owner's BRC-169 certificate handoff, acquire and prove it with this connected agent wallet, and reveal its restrictions to the specified Sigma verifier. Imports a certificate and activates its existing delegation. Never pays, broadcasts, follows redirects, or retries an ambiguous POST. The subject keyring stays with the wallet.

Result

An MCP result containing the operation outcome as text, with structured content where supplied. Check isError before using it; an output schema is shown when registered.

Permissions

This operation can change wallet, account or service state. A connected wallet applies its own permissions. Guarded broadcasts also require broadcasting to be enabled; service authorization is separate from wallet approval.
