Agenttrust
Check trust scores and reputation for agent-to-agent counterparties before you wire payments or sensitive workflows.
Overview
Agenttrust is an MCP server for the Ship phase that lets agents query trust scores and reputation to verify agent-to-agent counterparties.
What is this MCP server?
- Trust scores and reputation data for the agent-to-agent economy
- Verify A2A counterparties via MCP before high-trust actions
- Public read operations; AGENTTRUST_API_KEY for writes
- Documented free tier: 100 writes per day
- npm agenttrust-mcp v0.1.0 with configurable AGENTTRUST_API_BASE for self-host
- Version 0.1.0; npm identifier agenttrust-mcp
- Free tier documented: 100 writes/day with API key
- Default API base: agenttrust-mcp-production.up.railway.app
What problem does it solve?
Agent marketplaces and A2A deals are opaque, so a solo builder risks wiring payments or data exchange to unknown or low-reputation agents.
Who is it for?
Indie builders launching agent-to-agent features who want a quick reputation layer inside Claude Code before go-live.
Skip if: Builders who only need web page text extraction or government contract discovery with no A2A trust concern.
What do I get? / Deliverables
After you register agenttrust-mcp, your agent can look up trust signals and optionally record reputation data before you ship risky integrations.
- Agent-queryable trust and reputation signals for A2A parties
- Optional write-side reputation updates within free-tier limits
