Look up a form ID by its short title.
AI agents call lookup_form_by_title to retrieve information from Nettskjema MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata (a form ID) based on a search parameter (title). It does not create, modify, delete, or execute operations. It is a simple directory/search function with no destructive or actionable consequences. Severity is low because the blast radius of misuse is limited to information disclosure of form identifiers, which are typically not sensitive in themselves.
From the tool's definition Tool description states 'Look up a form ID by its short title' — a retrieval operation with no side effects. The verb 'lookup' and the action of retrieving a form identifier indicate a read-only query operation.
