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 CISA KEV and dated FIRST EPSS data. Check source coverage and collection health, page through hosted revisions, or read changes after a saved cursor. Connect to https://excessionlabs.ai/mcp/cve over Streamable HTTP; no account or API key is required. Version filters match source assertions and do not evaluate whether an installed version falls within a vulnerability range. NVD and GitHub enrichment can be incomplete. Hosted history starts at the displayed cutover date; initial observations establish a monitoring baseline. The public MIT repository contains documentation and tool schemas. The hosted implementation is maintained separately.
