Measured tools (12)

• priorseal_get_capabilities read-only

  Read the live PriorSeal deployment capabilities before constructing a workflow.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• priorseal_prepare_authorization read-only

  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.

  Parameters:

  • input (required) — object — The complete PriorSeal authorization preparation request.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• priorseal_prepare_controlled_execution read-only

  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.

  Parameters:

  • input (required) — object — The complete controlled-execution preparation request.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• 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.

  Parameters:

  • input (required) — object — The complete signed PriorSeal authorization request.

  Hints: read-only no · destructive no · idempotent no · open-world yes

• priorseal_get_authorization read-only

  Read an accepted authorization by its identifier.

  Parameters:

  • authorizationId (required) — string — PriorSeal authorization identifier.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• 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.

  Parameters:

  • input (required) — object — The complete PriorSeal execution-observation request.

  Hints: read-only no · destructive no · idempotent no · open-world yes

• priorseal_get_observation_job read-only

  Read the durable status of an automatic finality-observation job.

  Parameters:

  • jobId (required) — string — PriorSeal observation job identifier.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• priorseal_get_receipt read-only

  Read a signed execution receipt by its identifier.

  Parameters:

  • receiptId (required) — string — PriorSeal receipt identifier.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• priorseal_get_evidence_bundle read-only

  Get a free x402 purchase handoff for the portable receipt evidence bundle. This MCP result never includes the paid bundle itself.

  Parameters:

  • receiptId (required) — string — PriorSeal receipt identifier.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• priorseal_get_evidence read-only

  Get a free x402 purchase handoff for the chain-neutral Evidence API envelope. This MCP result never includes the paid envelope itself.

  Parameters:

  • receiptId (required) — string — PriorSeal receipt identifier.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• priorseal_get_fresh_evidence_check read-only

  Get a free x402 purchase handoff for a newly signed, read-only chain re-observation of an authorization-bound receipt.

  Parameters:

  • receiptId (required) — string — PriorSeal receipt identifier.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• priorseal_verify_receipt read-only

  Convenience-verify a PriorSeal receipt with the deployment key registry. Independent local verification remains required for trust decisions.

  Parameters:

  • receipt (required) — object — Receipt object to verify.

  Hints: read-only yes · destructive no · idempotent yes · open-world no
