Variables d'environnement

  • WALLET_PRIVATE_KEY secret Optional. Key of a dedicated, low-balance Base wallet holding USDC; pays each call via x402. Unset = free preview (returns the 402 quote).
  • DYOE_MAX_PAYMENT_USD Optional per-call payment cap in USD (default 0.10). /review costs $15 and needs a higher cap.

dyoe-trust-mcp

MCP server for DYOE, the trust layer for AI agents. It gives Claude, Cursor or any MCP client 22 pay-per-call tools from agents.dyoeway.org: scam and fraud checks, payment pre-flight, wallet screening, policy approval and human sign-off, contact extraction, company research, and data tools. Every call settles in USDC on Base via x402. You need no account or API key.

  • Free preview by default. Without a wallet, each tool makes one unpaid request and returns the x402 payment requirements (HTTP 402: price, network, payTo). Nothing is signed or spent.
  • Paid mode. Set WALLET_PRIVATE_KEY to a dedicated, low-balance Base wallet holding USDC. The key stays on your machine (stdio) and signs each payment locally. Each call is capped at DYOE_MAX_PAYMENT_USD (default 0.10). Tools priced above the cap (dyoe_review, $15) are refused until you raise it.

Install

Claude Desktop

Add this to claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json, Windows: %APPDATA%\Claude\claude_desktop_config.json), then restart Claude:

{
  "mcpServers": {
    "dyoe": {
      "command": "npx",
      "args": ["-y", "dyoe-trust-mcp"],
      "env": {
        "WALLET_PRIVATE_KEY": "",
        "DYOE_MAX_PAYMENT_USD": "0.10"
      }
    }
  }
}

Leave WALLET_PRIVATE_KEY empty for preview mode. The .mcpb bundle from the GitHub releases also installs with one click (Settings > Extensions).

Cursor

Add this to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

{
  "mcpServers": {
    "dyoe": {
      "command": "npx",
      "args": ["-y", "dyoe-trust-mcp"],
      "env": { "WALLET_PRIVATE_KEY": "", "DYOE_MAX_PAYMENT_USD": "0.10" }
    }
  }
}

Tools (22)

Prices are what the endpoint charges per call. The live 402 is the authority, and every result reports the price it quoted.

dyoe_reputation$0.05DYOE Reputation History: Look up the track record of any domain or wallet: how many times it has been assessed, verdict history, times flagged, first and last seen, a reputation score and a signed credential — a credit score for counterparties. Computed only from DYOE's own logged prior assessments; thin history is labeled as such. Input: ?target=
dyoe_credential_org$0.10DYOE Org Credential: Issue a signed, independently verifiable credential that a business domain passed a trust check — returns verdict, trust_score and domain_age. Input: ?domain=

Safety

  • Use a burner wallet with a few dollars of USDC, never your main wallet.
  • The server signs only x402 payments for the tool you call, up to the per-call cap.
  • dyoe_approve and dyoe_review act on your behalf: they record an approval request with DYOE.
