"Resources and Tips for Writing Better R Code" matching MCP connectors:

Scan and fix a domain's email authentication - SPF, DMARC, DKIM, MX, blacklists, domain/SSL expiry. Eleven tools returning copy-paste records from a validating engine, never a guessed one, plus check_record to confirm a DNS change actually landed.

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

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

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.

Free self-serve Agent Passports for AI agents: signed, portable, offline-verifiable credentials.

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

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.

Portable identity, authority, trust receipts, and Vault secrets before sensitive AI actions.

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

Read-only MCP server for turva.dev, an agent-readiness audit and advisory service.

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

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

DMARC analytics for AI assistants — domain health, SPF/DKIM records, compliance stats, anomalies.

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.

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.

Query Microsoft Patch Tuesday security updates (MSRC) with EPSS and CISA KEV enrichment

One-step legal compliance for vibe-coded apps: privacy, terms, cookie banner and EU AI Act check.

Protects AI coding agents from installing malicious open source packages. Every npm and PyPI package is checked against SafeDep’s real-time threat intelligence before installation.

Independent static verification for exact immutable public GitHub commits.
