provenance-mcp
Check the wash-traffic risk of Algorand x402 endpoints before your agent pays them.
📊 The x402 Trust Index — our free public leaderboard: weekly Bazaar Wash Report + resale-authorization audits for 38 API brands.
Roughly half of x402 "agentic payment" activity is artificial — self-dealing loops, fresh-wallet farms, metronomic bots. Provenance reads the chain and tells your agent whether an endpoint's revenue is organic or fabricated, so it can decide before sending USDC.
Tools
check_endpoint_risk(address)— free quick verdict for any Algorand endpoint payTo address: risk level (low/medium/high/critical), 0–100 score, and the on-chain red flags (distinct-payer count, self-dealing payout loops, wallet ages, timing regularity, funding concentration).provenance_service_info()— service + paid-tier info.
Deep forensics are x402-paid on the same API: /score $0.05 · /report $0.50
(full 8-signal grade + facilitator drift) · /diligence $5.00.

Claude Code
claude mcp add provenance -- npx -y provenance-mcp
Claude Desktop / any MCP client (mcpServers config):
{
"mcpServers": {
"provenance": {
"command": "npx",
"args": ["-y", "provenance-mcp"]
}
}
}
Then ask your agent: “check the wash risk of Algorand endpoint <ADDRESS>”.
How it works
The hosted Provenance engine indexes USDC (ASA 31566704) payments on Algorand mainnet, enriches payer wallets (age, first funder, asset diversity, rekey auth-addr), clusters them (union-find over funding + shared-key links), and runs 8 wash-detection signals. Scores are point-in-time snapshots, anchored on-chain for tamper-evidence. Methodology: signals, not accusations — a high score means the revenue pattern is consistent with self-dealing, not that the operator is guilty of anything.

Building an agent that pays over x402? provenance-guard
wraps any x402-paying fetch and runs this same check automatically before any
money moves — one line, zero dependencies:
import { createGuard } from "provenance-guard";
const guarded = createGuard().guardedFetch(fetchWithPayment);
