Crest Counterparty Intelligence

Counterparty, credit, and token-risk intelligence for the x402 agent economy. Crest scores the code AND the people behind it, from a settlement graph no directory has.

Live MCP endpoint: https://data.crestsystems.ai/mcp (Streamable HTTP, no auth). On Smithery: crest/counterparty-intelligence.

Why

Before an agent pays a wallet, buys a token, or extends another agent credit, it needs to know what is on the other side. Most scanners read only the contract or only the balance. Crest reads the contract's powers (what it can do) and the reputation of the wallet that controls it (who holds the keys), and gates one by the other. The same powers are safe under a trusted issuer and a rug under an anonymous, drained wallet.

Tools

Tool	What it does
token_risk	Scan a Base token for rug / honeypot / mint-authority risk. Contract powers (mint, blacklist, pause, upgradeable) gated by the controlling wallet's reputation. Call before buying, swapping, or LPing.
crest_score	Two-axis creditworthiness for an x402 agent wallet: solvency (will it stay funded) + liveness (will it keep paying). Call before extending service or settlement risk.
agent_credit	Economic standing of an agent wallet: funded / active / low / drained, with a creditworthiness verdict.
agent_preflight	Pre-action risk gate. Call before any transfer, trade, or settlement.
check_counterparty	What is on the other side of an x402 payment: real service, buyer, relayer, or treasury.
pm_counterparty	Classify a Polymarket trader as sharp or dumb money.
onchain_profile	Quick public snapshot of any Base address (type, balance, tx count).

All tools are free and read-only. The deep scored reports are $0.05 x402 calls on Base. Not financial advice.

Run it yourself

This repository is a thin, read-only client over Crest's public preview endpoints. No keys, no database, no secrets.

npm install
node index.mjs        # listens on :8080, MCP at POST /mcp

Add to an MCP client (e.g. Claude Code) pointing at the hosted endpoint:

claude mcp add --transport http crest "https://data.crestsystems.ai/mcp"
