What pdf_to_images does on Tanod
AI agents call pdf_to_images to retrieve information from Tanod without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

|---|---|---|---|
dpi | integer | — | 36-300 (default 150). |
url | object | — | Public http(s) URL of the PDF (at most 20 MB; private, internal and IP-literal hosts are refused); or use pdf_base64. |
pages | object | — | Pages to render (default all; at most 20 per call). A closed selection of at most 5 pages is the lower price. |
format | string | — | png (default) or jpeg. |
output | string | — | base64 (default): inline. url: stored for 24 hours; link, metadata. |
grayscale | boolean | — | Render in grayscale. |

jpeg_quality | integer | — | JPEG quality (30-95, default 85). |

Why pdf_to_images is rated Low
Even though pdf_to_images only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

The rule that runs pdf_to_images safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Tanod, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pdf_to_images, this is the rule to start with:
pdf_to_images is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Tanod, apply this rule, and every pdf_to_images call is checked against it from then on.
