Agenttrust

bch1212/agenttrust-mcp

Gives Claude twelve tools to check agent reputation before your AI transacts with another AI. You can register agents, record successful or failed transactions, file disputes, endorse counterparties, and pull live trust scores computed from transaction history, success rate, account age, endorsements, and dispute records. Scores run 0 to 1000 with tier labels like PLATINUM or BRONZE. Everything lives in SQLite with no external dependencies. Public read calls let you search agents by capability or pull leaderboards. Write operations need an API key. Built for the agent-to-agent commerce layer where your autonomous system needs to verify who it's paying or handing data to before the deal goes through.

AgentTrust MCP

The trust layer for the A2A economy. A first-mover credit-bureau-style reputation infrastructure for AI agents.

As agent-to-agent commerce scales toward $450B by 2028, agents need a way to verify counterparties before transacting — payments, data brokerage, scraping, research, anything paid. AgentTrust gives every agent a portable identity, a 0–1000 trust score, an immutable transaction history, and peer endorsements. Other agents query it; humans verify it; disputes erode it.

Twelve MCP tools, one SQLite store, zero external dependencies. Drop-in compatible with the Anthropic MCP protocol.

Install

git clone <this repo> && cd mcp-agenttrust
