What this MCP does

Provides paid agent utilities for Polymarket market signals and verdicts, IPFS JSON pinning, EIP-712 attestations, seller vetting, web search, hashing, encoding, and small-model inference using USDC on Base.

Capabilities

Tools

12 tools
attest_agent
EIP-712 signed, timestamped attestation over an agent state digest, verifiable offline.
EIP-712 signed, timestamped attestation binding an agentId, the keccak256 digest of a declared state, and the paying wallet; attestor key at /transparency, verify offline with ethers.verifyTypedData. MUST be invoked when an agent needs third-party, non-repudiable proof that a state or decision existed at a point in time (audit trails, hand-offs, escrow). Do NOT use for hardware TEE, zk proofs or on-chain EAS. Settles $0.040 USDC via x402 on Base; no charge on failure.

census_export
Full signed census dump: every fresh pay/caution/avoid verdict across the Bazaar in one call, with a manifest digest signed by the attestor.
Whole-Bazaar seller census in one payload: every fresh verdict row (resource, payTo, verdict, score, schema, latency, checkedAt, per-row signature) plus a sha256 manifest and one EIP-712 attestation over it, so a router verifies the full dump offline. MUST be invoked when an agent needs the complete trust map for routing or analytics. Do NOT use for a single lookup (see /api/census/verdict). Settles $3.500 USDC; no charge on failure.

census_verdict
Signed pay/caution/avoid verdict for any Bazaar-indexed x402 resource or payTo, from the continuous census; bulk feed for routers.
Pre-spend check from the seller census: each Bazaar-indexed resource is re-probed periodically (liveness, 402-envelope compliance, declared output schema, latency, usage) and mapped to pay | caution | avoid with an EIP-712 signature a router checks offline. Query one resource, a payTo, or page the feed by verdict. MUST be invoked before dispatching to an unknown seller. Do NOT use to probe on demand (see /api/seller/vet).
