Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (10)

priorseal_accept_authorizationVerify 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.
priorseal_get_authorizationread-onlyRead an accepted authorization by its identifier.
priorseal_get_capabilitiesread-onlyRead the live PriorSeal deployment capabilities before constructing a workflow.
priorseal_get_evidence_bundleread-onlyExport the portable receipt evidence bundle and issuer key-discovery metadata.
priorseal_get_observation_jobread-onlyRead the durable status of an automatic finality-observation job.
priorseal_get_receiptread-onlyRead a signed execution receipt by its identifier.
priorseal_observe_executionPersist 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.
priorseal_prepare_authorizationread-onlyCanonicalize 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.
priorseal_prepare_controlled_executionread-onlyPrepare 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.
priorseal_verify_receiptread-onlyConvenience-verify a PriorSeal receipt with the deployment key registry. Independent local verification remains required for trust decisions.
