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.

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

    Scored across 12 tools

    Disambiguation4/5

    Most tools have distinct purposes, but there is some overlap between trust_review, trust_dispute, and trust_endorse, all of which affect an agent's score through different mechanisms. The descriptions help clarify, but an agent could potentially confuse which to use for positive or negative feedback.

    Naming Consistency4/5

    All tools share the consistent 'trust_' prefix, which makes the set easy to recognize. However, the suffixes mix verbs (lookup, register, verify, search, endorse, dispute) and nouns (challenge, evidence, transaction, history, review), making the naming pattern not strictly uniform.

    Tool Count5/5

    With 12 tools, the set is well-scoped for a trust registry. Each tool covers a specific aspect of the domain—registration, lookup, verification, feedback, evidence, disputes, endorsements, transactions, and history—without feeling bloated or too sparse.

    Completeness5/5

    The tool surface provides comprehensive coverage of trust management: registering agents, querying scores, searching, verifying identities, submitting reviews, evidence, disputes, endorsements, recording transactions, and viewing score history. No major gaps are apparent for the stated purpose.
