Implementation Reference

• src/mcp-server.js:196-217 (handler)

  The 'get_passport' tool handler is implemented within the createMcpServer function in src/mcp-server.js. It calls generatePassport and returns the signed agent passport.

  // --- Tool: get_passport ---
  server.tool(
    'get_passport',
    'Get a signed cross-protocol agent passport. Contains identity, stamp, reputation, A2A card, and MCP metadata — all Ed25519-signed.',
    {
      wallet_address: z.string().describe('Ethereum wallet address (0x...)'),
    },
    async ({ wallet_address }) => {
      const passport = generatePassport(wallet_address);
      if (!passport) {
        return { content: [{ type: 'text', text: JSON.stringify({
          error: 'No active agent found for this wallet',
          trusted: false,
          message: 'This wallet has no AgentStamp identity. Register for free to get a verifiable passport.',
          register_url: 'https://agentstamp.org/register',
        }) }] };
      }
      return {
        content: [{ type: 'text', text: JSON.stringify(passport, null, 2) }],
      };
    }
  );
