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 trustagent-mcp
Claude Code 
claude mcp add trustagent-counterparty-verification -e 'TRUSTAGENT_URL=https://trust-agent.io' -e 'TRUSTAGENT_WALLET_KEY=<your trustagent_wallet_key>' -e 'TRUSTAGENT_MAX_PER_CALL_USD=0.05' -e 'TRUSTAGENT_MAX_SESSION_USD=1.00' -- npx -y trustagent-mcp@0.1.2
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "trustagent-counterparty-verification": {
            "command": "npx",
            "args": [
                "-y",
                "trustagent-mcp@0.1.2"
            ],
            "env": {
                "TRUSTAGENT_URL": "https://trust-agent.io",
                "TRUSTAGENT_WALLET_KEY": "<your trustagent_wallet_key>",
                "TRUSTAGENT_MAX_PER_CALL_USD": "0.05",
                "TRUSTAGENT_MAX_SESSION_USD": "1.00"
            }
        }
    }
}

Environment variables

  • TRUSTAGENT_URL Service to query. Defaults to the hosted deployment.
  • TRUSTAGENT_WALLET_KEY secret Private key of a funded Base wallet. Enables the four paid tools, which settle per call in USDC over x402. Omit to run the free tools only — they need no wallet. Requires the optional peer dependency x402-fetch.
  • TRUSTAGENT_MAX_PER_CALL_USD Refuse any single paid call above this amount.
  • TRUSTAGENT_MAX_SESSION_USD Total spend ceiling across all paid calls in one session. A model looping on a retry is the realistic failure, and a per-call limit does not catch it.
