WHAT IT DOES

What fill_docx_template does on Tanod

AI agents use fill_docx_template to create or update resources in Tanod, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tanod environment.

Parameter	Type	Required	Description
`url`	object	—	Public http(s) URL of the DOCX template (at most 20 MB; private, internal and IP-literal hosts are refused); or use file_base64.
`data`	object	Yes	The values, a JSON object (at most 1 MB, 12 levels deep). {{name}} reads data["name"], {{customer.name}} data["customer"]["name"], {{items.0}} the first element
`output`	string	—	docx (default) or pdf (the filled file rendered by LibreOffice; priced higher).
`delivery`	string	—	base64 (default): inline. url: stored for 24 hours; link, metadata.
`file_base64`	object	—	The DOCX template as base64 (at most 10 MB decoded); or use url.

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs fill_docx_template 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 fill_docx_template, this is the rule to start with:

fill_docx_template Rate-limited

fill_docx_template 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.

What does the fill_docx_template tool do? +

pdfpeek: Fill the {{placeholders}} of a Word template with JSON data, as DOCX or PDF. For slides from JSON use build_pptx_deck. Returns the filled document, base64 in file (DOCX, or PDF with output=pdf; delivery=url gives a 24 h link); a placeholder with no value is left as written and listed in missing. {{name}} and dotted paths {{customer.name}} read data; a table row holding {{#items}} and {{/items}} repeats per list element (no nesting). Values go in as plain text, so format dates and numbers first. DOCX only. Encrypted or damaged files are a 422, over 15 MB of output a 413 (none charged). Typically 1-3 s for DOCX, 3-8 s for PDF.
