FOSSA REST API

The FOSSA REST API lets you build integrations and automate open source management workflows — manage projects, revisions, issues, users and teams, release groups, and reports; initiate binary scans; download attribution reports; and query the vulnerability database by CPE. Authenticates with an API token in the Authorization Bearer header over HTTPS.

  note: 'Renamed from MCPServer 2026-09-03 (roadmap#247): the manifest self-describes as status: candidate
    — a tool list derived from the published API contracts, not an existing server. The scorer already
    read the manifest and reported mcp_server correctly; the MCPServer type was crediting the artifact-type
    surfaces with a server that does not exist.'
