Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package @nikosble1926/agent-trust-mcp
Claude Code 
claude mcp add agent-trust-mcp -e 'EVM_PRIVATE_KEY=<your evm_private_key>' -e 'RESOURCE_SERVER_URL=https://trust.nsgoods.org' -- npx -y @nikosble1926/agent-trust-mcp@1.0.0

            }
        }
    }
}

Environment variables

  • EVM_PRIVATE_KEY secret Optional. Base wallet private key (0x...) for a low-balance hot wallet with a little USDC. Required only for the paid tool; the free get_trust_preview works without it. Never use your main wallet.
  • RESOURCE_SERVER_URL Optional. Override the trust API base URL. Defaults to https://trust.nsgoods.org.

agent-trust-oracle

Read only, pay per call trust scores for ERC-8004 agents, served over the x402 protocol. Every response is a signed, verifiable verdict.

What this is (for AI agents): a pay per call HTTP 402 endpoint that returns a signed, machine readable trust score for an ERC-8004 agent. No accounts, no API keys. Pay USDC on Base, get a verdict you can verify yourself.

What it does

  • Returns a signed trust score for an agent, on demand, per call over HTTP 402
  • Read only on chain analytics across multiple EVM chains (Ethereum, Base, BSC, Mantle, Polygon)
  • Built for the ERC-8004 agent identity and reputation ecosystem
  • Free preview endpoint so you can see the shape before you pay

How it works

  • Signed with EIP-191; every verdict is canonicalized and independently verifiable
  • Settled per call in USDC on Base
  • You pay only for a successful 2xx response
  • Open source, MIT
