AI agents call get_pdf_form_elements to retrieve information from Pdf Tools without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_pdf_form_elements only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

This tool finds all form elements in a PDF document and returns their names and types. It can identify text fields, checkboxes, radio buttons, dropdown menus, and option lists. Inputs: - filePath: Path to the PDF file or file:// URL The tool returns information about all form elements found in the PDF including: - Name of each form element - Type of each form element (TextField, CheckBox, RadioGroup, Dropdown, OptionList) - Additional properties when available (like options for dropdowns and radio groups) Note: This tool only works with PDF forms that have defined form fields. It's useful for exploring forms before filling them with the fill_pdf_form tool.. It is categorised as a Read tool in the Pdf Tools MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for get_pdf_form_elements. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Pdf Tools MCP server.
get_pdf_form_elements is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_pdf_form_elements rule in your Intercept 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 Intercept policy for get_pdf_form_elements. 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.
get_pdf_form_elements is provided by the Pdf Tools MCP server (@mcp-apps/pdf-tools-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
