GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
34 security tools for AI agents: phishing links, exposure maps, DNS, SSL, PQC, history, pivots.
Monitor CVEs, packages, domains and IPs. CVE/EPSS/KEV, SBOM, DNS/TLS, IP lookups. No key, x402.
30 security tools + the Vigia agent to audit MCP servers before you connect.
The main MCP server has 10 tools, including six public, read-only CVE tools, site search and page reading. CVE results include source software/version evidence and available CISA KEV and dated FIRST EPSS data. The separate request_security_test action requires an agent key, consent and authorization. A no-account, read-only CVE-only endpoint is https://excessionlabs.ai/mcp/cve. Docs: https://excessionlabs.ai/cve-intelligence/.
Grade a page's HTTP security headers, search penetration testing guides and send a pentest request for a person. The read tools need no authentication; request_pentest needs a free agent key.
Free website privacy scanner for pre-consent cookies, trackers, consent, policy, and HTTPS/TLS.
30 security tools + the Vigía agent to audit MCP servers for prompt injection, SSRF, leaked secrets, auth bypass and more — scan before you connect.
Live security incidents, updated hourly from CISA KEV, critical GitHub security advisories, CVE records, vendor advisories and security news. For each one: what's affected, whether a fix exists, which versions fix it, and the sources. Check a lockfile or a whole repo and get the exact upgrade. Lockfiles are read in memory and never stored. Read-only MCP server, no auth
Free email checks: 24 blacklists, spoofing grade, redirects, spam test, WHOIS, BIMI, AI readiness.

Prompt-injection scanner for agents: risk score, categories and spans for text, pages, MCP tools
Scan text, web pages and MCP tool descriptions for prompt injection and tool poisoning before your agent trusts them. Free preview and MCP tool scan_text; full scans via x402 at $0.003 USDC on Base.
Triage a CVE: how severe it is, whether it is exploited, and how likely exploitation is.
Fetches a public http(s) URL (GET, up to 5 redirects, 10s timeout, body never read) and grades its security headers A+ to F: score, present and missing headers (HSTS, CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy), per-header findings with copy-paste fix values, and cookie flag issues. Passive, SSRF-guarded. Pay-per-call via x402 ($0.01 USDC on Base); initialize and tools/list are free.
Check text before your agent reads it: hidden instructions, invisible text and links that leak data.

Pay-per-call agent tools: PDF, OCR, translation, news search, prediction markets, web, chain reads.
Free AI test helpers: injection inputs, OWASP mapping, release plans, response and tool-call packs.
Hosted, no-auth endpoint of feldspar-scan: free deterministic security scan of a public git repository (OSV.dev vulnerable dependencies, secret patterns, config lint) as structured JSON. Tools: scan_repository(url), audit_pricing(). Stateless streamable-HTTP JSON-RPC, rate-limited. Source: https://github.com/project-feldspar-resources/feldspar-scan (MIT).
