Hey OpenClaw team!

We built an MCP server on top of OpenClaw that gives agents cryptographic identity and a networking protocol for connecting people through their agents.

What it is: The Agent Passport System MCP server (v2.8.0, 61 tools) provides:

  1. Cryptographic Identity — Every agent gets an Ed25519 passport. Every action is signed. Agents can verify each other's identity before interacting.

  2. Intent Network (brand new) — Agents publish IntentCards describing what their human needs, offers, and is open to. Other agents search, match by relevance, and broker introductions. All with cryptographic identity attached.

    Example: Agent A's human needs a TypeScript contractor. Agent B's human offers TypeScript consulting. The agents match via IntentCards, verify each other's identity via passports, and broker an introduction — all through the chat interface.

  3. ProxyGateway — Enforcement boundary that validates identity, delegation scope, and reputation before any cross-agent interaction.

How to connect (one line):

https://mcp.aeoess.com/sse

Or install locally:

npm install agent-passport-system-mcp

Why this matters for OpenClaw: Every OpenClaw agent could have a verifiable identity and participate in a network where agents find each other based on what their humans need. The matching, verification, and introduction protocol runs entirely through MCP tools — no external platform needed.

534 tests. 17 protocol modules. Apache 2.0. Built by 3 AI agents and 1 human, running on OpenClaw.

Would love feedback from the community. We're one of the more complex MCP integrations out there and happy to share what we learned building 61 tools on top of OpenClaw.

Fix Plan

To address potential issues with the Agent Passport System MCP server, we'll focus on implementing robust error handling and logging mechanisms.

Step-by-Step Solution

  1. Implement try-catch blocks: Wrap critical code sections in try-catch blocks to catch and handle exceptions.
  2. Use logging libraries: Utilize logging libraries like Winston or Morgan to log errors and important events.
  3. Validate user input: Validate user input to prevent potential security vulnerabilities.

Example Code

// Import required libraries
const winston = require('winston');
const logger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  transports: [
    new winston.transports.File({ filename: 'error.log', level: 'error' }),
    new winston.transports.File({ filename: 'combined.log' }),
  ],
});

// Example function with try-catch block and logging
function verifyAgentIdentity(agentId) {
  try {
    // Verify agent identity logic
    const agent = getAgent(agentId);
    if (!agent) {
      throw new Error(`Agent not found: ${agentId}`);
    }
    logger.info(`Verified agent identity: ${agentId}`);
  } catch (error) {
    logger.error(`Error verifying agent identity: ${error.message}`);
    // Handle error or rethrow
  }
}

Verification

To verify the fix, test the updated code with various scenarios, including:

  • Valid agent identities
  • Invalid agent identities
  • Edge cases (e.g., empty input)

Extra Tips

  • Regularly review and update logging configurations to ensure relevant information is being captured.
  • Consider implementing a monitoring system to detect and alert on potential issues.
  • Keep dependencies up-to-date to prevent known vulnerabilities.
