"Information about Claude Code" matching MCP connectors:

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

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.

Pay-per-call cybersecurity for AI agents: vuln scans, threat intel, compliance, code security.

Query WHOIS/RDAP information for domains, IP addresses, CIDR prefixes and ASNs. Self-hostable.

Deterministic AI liability attribution with Bitcoin-anchored proof certificates.

Deterministic AI-liability attribution: signed, Bitcoin-anchored vendor/deployer/user fault split.

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

Encrypted store for API keys and database URLs your code needs. Use them without reading them.

No-account public website privacy risk scans with 20 new scans/day and free recent-result reuse.

Scans text for personally identifiable information — emails, phone numbers, SSNs, credit card numbers, physical addresses, names — and returns a redacted version. Built for agents sanitizing user content, support tickets, logs, or documents before storage, sharing, or feeding into another LLM call. Pay-per-call via x402 (USDC on Base): $0.01/call, no account or API key. tools/list and /openapi.json are free for discovery.

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

Threat modeling, code/cloud/pipeline scanning, shadow-AI discovery, compliance checks and fixes.

SSL/TLS scanning, free Let's Encrypt issuance, and certificate-expiry monitoring.

Screen a name against the U.S. Treasury OFAC SDN list. Information, not a compliance determination.

MCP gateway with 10 tools for code analysis, architecture, package audit & security.

MCP server for static security analysis of Android source code

Cloudflare Workers MCP server: code-pattern-risk-scanner

The internet's largest queryable infrastructure graph — 7.39 billion nodes, 39 billion edges, 5.6 million threat-intelligence relationships. Pivot from any IP, domain, or ASN across DNS, BGP, WHOIS, GeoIP, and threat intel in a single Cypher query. Most threat-intel and OSINT APIs are point lookups: you ask about one indicator, you get one record. Investigations don't work that way — you start from one suspicious domain and need to trace its hosting, its sibling domains, its registrar, its email

Managed MCP gateway for PostgreSQL. Connect Cursor, Claude Desktop, VS Code, and Windsurf to your database with per-table permissions, encrypted credentials, and a full query audit trail. OAuth 2.0 authentication, free tier available.
