Scan code for quantum-vulnerable cryptography and get NIST post-quantum migration guidance.

Verify claims, resolve FIGI identity, extract claims, and sign x402 delivery receipts over MCP.

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.

Discovery, OAuth, project operations, and exact project MCP handoff for Spala backend projects.

Scan and fix email auth (SPF, DMARC, DKIM, MX, blacklists, expiry) + DNS checks. Validated fixes.

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.

Runtime permission, approval, and audit layer for AI agent tool execution.

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.

Free website privacy scanner for pre-consent cookies, trackers, consent, policy, and HTTPS/TLS.

Read AFMR failure modes and discover scoped attestation and lift-evidence contracts.

Audit MCP configs and skill files for over-broad scope and injection risk. 6 of 8 free.

Email posture for any domain: can it receive mail, can it be spoofed? MX, SPF and DMARC.

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