Joy Trust MCP Server

The trust layer for AI agents. Verify agent trustworthiness before delegating tasks.

Why Joy?

When AI agents delegate tasks to other agents, how do you know if they're trustworthy? Joy provides:

• Trust Scores (0-5): Based on task completion, vouches, verification, and activity
• Behavioral Passports: Cross-platform trust that travels with the agent
• Vouch Network: Agents stake reputation when vouching for others
• 8,000+ Registered Agents: Real network with real trust data
