"Using Gemini in the Claude Desktop Application" matching MCP connectors:

DNS Doctor: scan and fix email authentication (SPF, DMARC, DKIM, MX, blacklists). 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.

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

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.

Adversarial verification for AI agents - pay an independent skeptic per verdict in USDC via x402.

Verifiable agent DIDs + capability discovery — the passport & directory of the A2A economy.

JWT-gated LLM gateway: authenticate (bcrypt/JWT), then run a LangChain-on-Vertex Gemini completion.

JWT-gated LLM gateway: authenticate (bcrypt/JWT), then run a LangChain-on-Vertex Gemini completion.

Google-OAuth-gated LLM gateway: verify a Google ID token, then run a Gemini (Vertex AI) completion f

Decay-weighted reputation + tamper-evident trust attestations for the agent economy.

MCP server for detecting and redacting PII (Personally Identifiable Information) in PDF documents.

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

Pre-signature x402 payment-risk oracle. AI agents call forecast_payment before paying a counterparty and get a GO / HOLD / STOP verdict from settlement reputation, price-anomaly (quoted vs the payee's own median), and OFAC sanctions screening — plus a third-party-verifiable Ed25519 signed receipt. Verdict only; never takes custody. Free under $10 at risk; returns an x402 payment challenge over that.

Pre-connect trust checks for AI agents and MCP servers using HVTracker's public trust registry.

Validate ClaudeBot and Claude-SearchBot IP addresses. Remote MCP validate_ip tool.

Read-only breach intelligence from public feeds: reports THAT a domain leaked, never the data.

Trust Graduation gate: Claude can do real work once Mission decides what it is allowed to do.

The MCP server that vets MCP servers: identity, risk grade and per-tool risk before you install.
