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/.
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.
Safety checks before you sign, pay or install: contract, token and package scans, phishing, OFAC.
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
