TrustMesh MCP Server

Trust scoring for AI agents via Model Context Protocol.

npm version

What is this?

An MCP server that gives AI agents (Claude, Cursor, Windsurf, etc.) the ability to check trust scores and rate interactions with other agents — before transacting.

Why?

When autonomous agents trade APIs, data, and services, they need to know: can I trust this counterparty? TrustMesh provides the reputation layer that's missing from the AI agent ecosystem.

→ Trust Score: 0.23 (🔴 LOW)
→ ⚠️ WARNING: This agent has very low trust. Proceed with extreme caution.

After a successful API call:

> Rate agent-weather-api 0.9 for delivered-api-data
→ Rating recorded. Trust graph updated.

Batch check counterparties:

> Check scores for [agent-a, agent-b, agent-c]
→ 🟢 agent-a: 0.85
→ 🟡 agent-b: 0.52
→ 🔴 agent-c: 0.18
