Create a new PDF form with interactive fields
AI agents use create_form_pdf to create or update resources in MCP PDF — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP PDF environment.
This tool creates new PDF documents, which is a reversible write operation. It does not execute arbitrary code, delete data, or cause financial impact. The severity is medium because malicious creation of deceptive forms could be used for phishing or fraud, but the operation itself is reversible and the blast radius is limited to document creation rather than system-level effects.
From the tool's definition Tool name 'create_form_pdf' and description 'Create a new PDF form with interactive fields' indicate creation of new PDF documents with form elements.
Documented attack patterns abuse exactly the kind of access create_form_pdf gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP PDF, and nothing reaches the server without passing your rules. This is the rule we recommend for create_form_pdf:
{
"version": "1",
"default": "deny",
"tools": {
"create_form_pdf": {
"limits": [
{
"counter": "create_form_pdf_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_form_pdf 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.

Yes. Add a rate_limit block to the create_form_pdf rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for create_form_pdf. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
create_form_pdf is provided by the MCP PDF MCP server (rsp2k/mcp-pdf). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP PDF, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
