Tools by question

Which of the 31 tools answers which question, how they are grouped, and the shaped response sizes measured for a large advisory.

Updated 02 Nov 2026Checked against mcp-server@1725a04

Each tool is built around a question rather than an endpoint. Several call more than one vdb-api route and compose the result, and all of them shape the response before it reaches the model. Every parameter and default is on the Tool reference.

Every result reports its own numbers in _meta["vulnetix/shaping"]. See Result metadata.

Errors are results

A tool that cannot answer returns a normal result with isError: true and a message aimed at the agent. A quota error says not to retry; a credential error says which header to set. See Errors.
