Excession Labs CVE intelligence

Excession Labs hosts a public CVE intelligence MCP connector with six read-only tools. Search by text, vendor, product, package, ecosystem or a literal source version. Read CVE details, source references, affected-software evidence and available KEV and EPSS data. Check source coverage and collection health, page through hosted revisions, or read changes after a saved cursor. A hosted collector runs every ten minutes in bounded batches; source schedules and catch-up differ. The connector is free and needs no account or API key. Version filters match source assertions; they do not evaluate whether an installed version falls within a vulnerability range. Hosted history starts at the displayed cutover date, and initial observations establish a monitoring baseline.
