Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Crest Counterparty Intelligence assess token risk for 0x4ed4e862860bed51a9570b96d89af5e1b0efefed"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.
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.

Tool | What it does |
| 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. |
| 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. |
| Economic standing of an agent wallet: funded / active / low / drained, with a creditworthiness verdict. |
| Pre-action risk gate. Call before any transfer, trade, or settlement. |
| What is on the other side of an x402 payment: real service, buyer, relayer, or treasury. |
| Classify a Polymarket trader as sharp or dumb money. |
| 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.
