## Tools (as reported by the server, not verified)

- `priorseal\_get\_capabilities`: Read the live PriorSeal deployment capabilities before constructing a workflow.
- `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.
- `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.
- `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.
- `priorseal\_get\_authorization`: Read an accepted authorization by its identifier.
- `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.
- `priorseal\_get\_observation\_job`: Read the durable status of an automatic finality-observation job.
- `priorseal\_get\_receipt`: Read a signed execution receipt by its identifier.
- `priorseal\_get\_evidence\_bundle`: Get a free x402 purchase handoff for the portable receipt evidence bundle. This MCP result never includes the paid bundle itself.
- `priorseal\_get\_evidence`: Get a free x402 purchase handoff for the chain-neutral Evidence API envelope. This MCP result never includes the paid envelope itself.
- `priorseal\_get\_fresh\_evidence\_check`: Get a free x402 purchase handoff for a newly signed, read-only chain re-observation of an authorization-bound receipt.
- `priorseal\_verify\_receipt`: Convenience-verify a PriorSeal receipt with the deployment key registry. Independent local verification remains required for trust decisions.
