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 →
list_detectors ~20
List the PII and credential detectors this scanner runs
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
scan_base64 ~128
Scan a document given as base64 (an attachment, an image a tool returned) for PII and credentials. The type is detected from the bytes.
| Name | Type | Req | Description |
|---|---|---|---|
| data | string | yes | Base64 bytes (a data: URL prefix is allowed) |
| include | array | – | Opt-in detectors: ip_address, mac_address, plate_tr |

| languages | array | – | Tesseract languages, default ["tur", "eng"] |
| ocr | boolean | – | OCR images and PDF pages without a text layer (default true; needs tesseract.js) |
No output schema declared.
No examples provided.
scan_document ~168
Find PII (TC Kimlik No, IBAN, card, passport, e-mail, phone, address…) and credentials inside a PDF, an image (screenshot, scanned page) or a text file on disk, before it is given to an LLM. PDFs are read from their text layer; images and scanned pages with OCR (Turkish and English).
