priorseal_get_capabilities | Read the live PriorSeal deployment capabilities before constructing a workflow. params: none |
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. params: input* |
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. params: input* |
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. params: input* |
priorseal_get_authorization | Read an accepted authorization by its identifier. params: authorizationId* |
priorseal_observe_execution | Persist an observation request for an already-submitted EVM or Solana transaction, then issue evidence when configured observation completes. A successful metered observation includes its first portable evidence bundle. This can consume configured Agent credits; send an idempotency key. It never broadcasts a transaction. params: input* |
priorseal_get_observation_job | Read the durable status of an automatic finality-observation job. params: jobId* |
priorseal_get_receipt | Read a signed execution receipt by its identifier. params: receiptId* |
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. params: receiptId* |
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. params: receiptId* |
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. params: receiptId* |
priorseal_verify_receipt | Convenience-verify a PriorSeal receipt with the deployment key registry. Independent local verification remains required for trust decisions. params: receipt* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
