    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 455 ms over 2 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 510 ms over 2 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    2 of 2 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Pass
    Stable tool list

    No tool was removed and no required parameter was added in the last 30 days.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured

Capabilities

Tools 12

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.

Discovered
priorseal_get_authorization

Read an accepted authorization by its identifier.

Discovered
priorseal_get_capabilities

Read the live PriorSeal deployment capabilities before constructing a workflow.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
priorseal_get_observation_job

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

Discovered
priorseal_get_receipt

Read a signed execution receipt by its identifier.

Discovered
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.

Discovered
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.

Discovered
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.

Discovered
priorseal_verify_receipt

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