Scored across 2 tools
The two tools serve clearly different actions: one retrieves a counterparty's reputation history, the other validates a JSON payload against a schema. There is mild conceptual overlap because both concern 'verification' and both return signed artifacts, which could momentarily confuse an agent, but the descriptions make the boundary workable.
Both names follow a clean verb_noun snake_case pattern (get_verification_record, verify_schema), with predictable verb choices that map directly onto their actions. No style mixing or vague naming.
Two tools is on the thin side for a server, even a narrowly scoped one; the surface feels like a minimal pair of endpoints rather than a fully scoped toolset. Each tool does earn its place, but there is little redundancy or supporting operations.
The buyer-side workflow (check reputation, validate output before paying) is covered, but the seller side is missing: there is no way to submit or publish your own output/attestation to build a record, and no operation to list or retrieve past checks and receipts. These are notable gaps for a trust/reputation service.
Available Tools
2 toolsget_verification_recordARead-onlyInspect
AI agent reputation and trust score: check an AI agent's verification record before you hire it, rely on its output or pay it. Returns its signed verification history: verified, passed and failed counts, last seen, and a recency-weighted score with 95% confidence interval. Check a counterparty before you pay, or see the record buyers will see. AI Agent Scores: $0.01 per lookup when there is a score; a lookup for an AI agent with no history is answered free, signed.
Inputs: agent_id (required).
verify_schemaAInspect
Independent check of AI agent output before you pay: verify and validate an AI agent's JSON against your JSON Schema and business rules, for example validate an invoice, check its total, or confirm a deliverable meets the agreed schema before you accept it. Checks structure, formats, ranges, and cross-field rules such as 'line totals must equal the total.' Returns pass/fail, % of checks passed, fix hints, and an Ed25519-signed attestation and receipt you can show as evidence of why you paid or refused. 1,000 free checks a day per caller, then $0.02 per check (x402, USDC on Base or Solana).
Inputs: task_id (required), expected_schema (required), submitted_output (required), rules, +5 more.
