Which MCP Server Should You Choose?
Choose Trustscoreagent when:
You need dedicated capabilities in the Security domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Primary tools included: Trust scores for URLs, domains, and DIDs, Post-call service rating submission, Service listing with sorting, filtering, and pagination.
Check the reputation of an AI microservice or public API before calling it, and submit ratings afterward — from a free, open trust registry (no account or API key). Scores combine Bayesian reputation and EigenTrust, strengthened by cryptographically signed service receipts and a Merkle audit trail. Install: npx -y @trustscoreagent/mcp-server.
Trust & safety layer for x402 agent payments: before your agent pays an x402 endpoint, verify it is safe — liveness, scam/anomaly scan (payTo hijack, bait-and-switch, honeypot), and on-chain receiver verification. 70% of x402 endpoints are dead or scams; only half of "healthy" listings work. Free /verify + an open Trust Score. npx -y pulsefeed-x402-mcp
