Tools
| Tool | Description | Behaviour |
|---|---|---|
| priorseal_accept_authorization | Verify and persist a principal-signed authorization. This can consume configured Agent credits and changes service state; send an idempotency key. It never signs, submits, or executes a transaction. | Changes data |
| priorseal_get_authorization | Read an accepted authorization by its identifier. | Read-only |
| priorseal_get_capabilities | Read the live PriorSeal deployment capabilities before constructing a workflow. | Read-only |
| priorseal_get_evidence_bundle | Export the portable receipt evidence bundle and issuer key-discovery metadata. | Read-only |
| priorseal_get_observation_job | Read the durable status of an automatic finality-observation job. | Read-only |
| priorseal_get_receipt | Read a signed execution receipt by its identifier. | Read-only |
| priorseal_observe_execution | Persist an observation request for an already-submitted EVM or Solana transaction, then issue evidence when configured observation completes. This can consume configured Agent credits; send an idempotency key. It never broadcasts a transaction. | Changes data |
| priorseal_prepare_authorization | Canonicalize a bounded authorization and return the exact EIP-712 typed data or Solana message for a human-controlled principal to sign. This is read-only and never signs, submits, or executes a transaction. | Read-only |
| priorseal_prepare_controlled_execution | Prepare a bounded authorization together with the deployment capabilities and a safe, explicit handoff plan. A human-controlled principal must still sign; this never accepts an authorization, signs, submits, or executes a transaction. | Read-only |
| priorseal_verify_receipt | Convenience-verify a PriorSeal receipt with the deployment key registry. Independent local verification remains required for trust decisions. | Read-only |
