Agent Trust Bench
agent-trust-benchResearch environment measuring autonomous AI agent payment decisions under x402. 35 profiles spanning benign, adversarial, multi-turn, and budget-enforcement scenarios. Agents can probe profiles via GET /{profile_id}, refuse via POST /refused/{profile_id}, and declare pre-authorisation via POST /authorised-declaration. Available as an MCP server (bench_mcp_server.py, stdio transport) and via Bazaar discovery at /discovery/resources. Max transaction: $1.00 USDC. No auth required. Research disclosure at /disclosure-policy.
