GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
Honeypot probe data: IP reputation, scanners, CVE probing, TLS and SSH fingerprints.
Find hidden Unicode in text or files: ASCII smuggling decoded, bidi overrides, look-alike letters.
CVE with EPSS and CISA KEV, package risk, software EOL, domain and IP reports, pay per call
External checks of TLS, HTTP, email domain, DNS, ports, blocklists and domain expiry
Adversarial testing for AI agents that move money: engine battery, Ed25519-sealed verdict reports.
Code security scanner for founders and small teams: leaked secrets, missing RLS, injection, CVEs
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/.
Calculate and validate CVSS 2.0, 3.0, 3.1, and 4.0 base scores.
Sourced data on 66 penetration testing providers: scope, delivery, published prices, retests. Read-only. Excession Labs publishes it and is one of the rows.
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.
Check a package version for known vulnerabilities and Packagist release facts.
Safety checks before you sign, pay or install: contract, token and package scans, phishing, OFAC.
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.
Real-time token contract safety scanner and honeypot auditor via x402 on Base.
30 security tools for AI agents: phishing links, exposure maps, DNS, SSL, PQC, history, pivots.
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.
CVSS Calculator MCP is a lightweight MCP server that enables AI agents to accurately calculate CVSS Base Scores and severity ratings. Supports CVSS 2.0, 3.0, 3.1, and 4.0 for vulnerability assessment, penetration testing, bug bounty hunting, and security reporting.
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.
Queries live Google OSV.dev vulnerability intelligence for any PyPI, npm, Go, or Rust crate and re
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.
Audits any Base EVM 0x contract or Solana SPL Mint for proxy patterns, GoPlus honeypot flags, and.
Check text before your agent reads it: hidden instructions, invisible text and links that leak data.
Scan a site or AI-built app for exposed databases, keys and MCP endpoints, then verify the fixes.
Find hidden Unicode (zero-width, bidi, tag payloads), homoglyphs and lookalike names in text.
Test your AI agents for security and safety weaknesses, and re-verify the fixes.
Passive OSINT and security recon: DNS, TLS, email posture, IP reputation, CVE/KEV, CT logs.
Inspects live IPv4/IPv6 DNS resolution, TLS certificate issuer/expiry, and HTTP security grade.
