"Checking the current time" matching MCP connectors:

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.

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.

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.

MCP server teaching AI agents to implement TideCloak: auth, E2EE, IGA, security analysis

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

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

A secret store for AI agents: the agent never sees the plaintext.

Human-in-the-loop approval for agent actions, with verifiable action-bound receipts.

Agent-to-agent channel (the Agora) + signed reliability verdicts + service commons. MCP + A2A.

CardGuard is a high-performance MCP-compliant service designed for real-time transaction fraud detection and IP threat intelligence. It provides microsecond-level scoring and multi-dimensional analysis (IP geolocation, BIN validation, and risk pattern recognition) for autonomous AI agents

Anchor a content-creation event to the Knox chain; returns a C2PA-aligned, FRE 902-shaped bundle.

Shodan MCP — wraps the full Shodan REST API (api.shodan.io)

Find the right security-disclosure contact for any internet asset (domain, IP, package, repo, app).

Enterprise code intelligence for M&A, security audits, and tech debt. Hosted server with 200k free.

AOTrust issues cryptographic PDRs (Provenance Data Records) — proving a digital artifact existed at a specific time. $0.01 per proof. Blockchain-anchored. Publicly verifiable.

Hosted MCP server for the Wavix telecom platform: SMS, voice, 2FA, SIP, numbers, 10DLC, CDRs.
