"Developing agents with expertise in the latest documentation" matching MCP connectors:

Read-only breach intel, full history 2007-today: reports THAT an org was breached, never the data.

Identity infrastructure for the AI economy. Confirms if someone is known; returns inferred traits.

Rank agents; signed machine messages + wallet gates via x402; free verifiable agent passports.

Neutral fairness computation for agents: two or more parties submit sealed inputs, a published deterministic algorithm runs (fair division, verifiable random selection, Shapley shares), and every party receives an identical signed certificate anyone can re-run and verify for free.

Verify anything: email, phone, domain, URL and IBAN validation, phishing/malware URL screening, and OFAC sanctions checks. Pay-per-check in USDC on Base via x402 — no signup, no API keys.

Public data intelligence for AI agents — CVE, compliance, patents, contracts, domains.

Hosted, OAuth-gated endpoint for quantakrypto's post-quantum crypto tools: scan code for quantum-vulnerable cryptography (RSA/ECDH/ECDSA/DH) and get NIST ML-KEM/ML-DSA/SLH-DSA migration guidance over authenticated HTTP — nothing to install. Sign-in required (Google/GitHub/email). Same tools as the open-source @quantakrypto/mcp server; source at github.com/quantakrypto/pqc-tools.

Scan public websites for privacy, cookie, tracker, consent, policy, and disclosure risk signals. Start instantly with zero-auth Light mode—no account or API key required.

Pay-per-call safety checks for AI agents: screen a crypto address or URL before you transact.

Governance firewall for autonomous AI agents. Intercept every agent action in real time, enforce configurable rules, and block violations before they execute.

The PropelAuth Integration MCP Server helps you and your favorite AI agent integrate PropelAuth as quickly and easily as possible into your project. Whether you're integrating PropelAuth into your Next.js project or your FastAPI backend, the Integration MCP Server will ensure your AI agent has the best context possible for a successful integration.

Verifiable provenance for AI agents — ZK proofs over confidential documents, no plaintext exposure.

Trusgent MCP — Trust Layer for AI agents. HK registry + Agent Cards. Default: get_merged_profile.

One read-only public-page readiness check with a signed, recheckable evidence receipt.

IOCs (URLs, domains, IPs, hashes) shared by the infosec community on X/Twitter. No auth, CC0.

Twelve tools: token, wallet, contract and site security. Two free, the rest $1 in USDC over x402.

Per-transaction crypto trade validator for AI agents. Returns deterministic PROCEED / CAUTION / BLOCK verdicts using WaveGuard anomaly detection, history checks, and rug-pull risk analysis.

Evidence-backed x402 web verification for AI agents, with auditable decisions for every condition.

Authorize x402 payments before signing with request-bound, signed safety decisions.

DNS and email security: check SPF, DKIM, DMARC, DNSSEC, DANE and build the records. 45 tools.
