Post-quantum readiness for AI coding agents: scan code for quantum-vulnerable cryptography (RSA/ECDH/ECDSA/DH), explain the harvest-now-decrypt-later exposure, get NIST ML-KEM/ML-DSA/SLH-DSA (and hybrid) migration guidance, verify fixes, and check dependencies. Content-based/advisory tools only. Run local (`npx @quantakrypto/mcp`) or the hosted OAuth endpoint at [mcp.quantakrypto.com](https://mcp.quantakrypto.com).

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`.

Your AI agent doesn't know what's broken in production. This fixes that. Last9 MCP Server connects Claude, Cursor, Windsurf, and any other MCP-capable AI assistant directly to your production observability data — logs, metrics, traces, exceptions, database queries, alerts, and deployments. The agent stops guessing and starts reading the actual signal. No binary to install. No tokens to manage. One URL, OAuth in your browser, done. Find your org slug in your Last9 URL: app.last9.io/<org_slug>/... Type /mcp, select last9, authenticate. That's it.
