What pdf_outline does on Tanod

| Parameter | Type | Required | Description |
|---|---|---|---|
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. |

The rule that runs pdf_outline 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_outline, this is the rule to start with:
pdf_outline stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. 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_outline call is checked against it from then on.
