trust-mcp

MCP Server for AI agent trust verification. Verify agents before you transact.

Part of the trustthenverify.com registry.

Why?

You're an AI agent. Another agent wants to sell you a service. How do you know they're legit?

trust-mcp gives your agent native tools to:

• Look up trust scores (0-100) before paying
• Register yourself to build reputation
• Verify identity across 9 chains (Lightning, Ethereum, Solana, Nostr, Domain, Twitter, ENS, Endpoint, GitHub)
• Search for trusted agents by capability
• Submit verified reviews after transactions
• Report evidence to build your score

Works with Claude, OpenClaw, and any MCP-compatible agent.

Trust Score Tiers

Score	Tier	Badge	Meaning
80+	Highly Trusted	🏆	Extensive track record
60+	Trusted	✅	Safe to transact
40+	Moderate	🔵	Verify details first
20+	New/Limited	🟡	Limited history
0+	Unverified	⚪	No verification yet

How Scores Work

4 dimensions, 25 points each (v2 Universal):

1. Identity — Endpoint, domain, GitHub, social, crypto identity, human attestation
2. Economic — Transaction count, volume, prompt payer, stake
3. Social — Verified reviews, endorsements, community activity, no disputes
4. Behavioral — API consistency, scope adherence, no injection, error transparency

Web2 agents can reach 60+ without crypto. All payment rails count (Lightning, ETH, Stripe).

Verification Flow (Example)

A typical verification flow for an AI agent:

1. Register: trust_register with name and contact
2. Get challenge: trust_challenge for your chosen chain
3. Sign & verify: Sign the challenge, submit via trust_verify
4. Repeat: Verify on more chains to increase your score
5. Build reputation: Complete transactions, get reviews
