The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
screen_export_control ~218
Screen a company or person name against the official US Consolidated Screening List (BIS Entity List, Denied Persons, MEU, ITAR Debarred, Treasury SDN/SSI/CMIC; 11 lists).
