"An overview of OSINT (Open Source Intelligence)" matching MCP connectors:

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

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.

530 MCP tools across 561 fintech tools: ChainGraph AP2 decisions, execution_hash. Zero PII.

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.

Cited EU & global law, regulations & security frameworks via Ansvar Gateway. OAuth, free + paid.

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

Verify x402 payment endpoints before an AI agent pays: scam scan, on-chain checks, trust scores.

Confirms an AI agent/service is who it claims to be (domain + agent-card + MCP handshake).

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

Audits NEXUS's own x402 payment logs against its own delivery logs and issues a signed proof-of-deli

Zero-install remote MCP server for proof-of-existence file attestation.

Verify VerixID proof-of-existence records and optionally prove ownership.

Capture a web source, or seal a hash you hold, into a signed receipt anyone can verify offline.

Query 90 days of honeypot probe data: IP reputation, scanners, CVE probing, TLS/SSH fingerprints.

Open weekly security base rates (CC BY 4.0), plus live DMARC, takeover and WHOIS checks.

CSOAI (UK 16939677) GSPC measurement over MCP: assess, board (13 of 14), verify cards.

Check how many years of verifiable history a person has behind accounts they already own.

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

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