AI agents use docapi_generate_pdf to create or modify resources in Docapi. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call docapi_generate_pdf repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Docapi.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Convert HTML to a PDF using DocAPI's headless Chromium renderer. Full CSS support: Flexbox, Grid, custom fonts, gradients, shadows. Args: - html (string): HTML to render. Inline styles and <style> tags work. Google Fonts URLs supported. - format ('A4' | 'Letter' | 'Legal' | 'Tabloid'): Paper size. Default: 'A4'. - landscape (boolean): Landscape orientation. Default: false. - margin_inches (number): Page margin in inches, 0–4. Default: 0.5. - print_background (boolean): Render background colors/images. Default: true. Returns: Base64-encoded PDF. You can save it to disk with a file writing tool. Errors: - 401: Invalid API key - 402: Credits exhausted (agent accounts) — send USDC to top up - 429: Monthly limit exceeded — upgrade plan at https://www.docapi.co/pricing. It is categorised as a Write tool in the Docapi MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Docapi MCP server in PolicyLayer and add a rule for docapi_generate_pdf: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Docapi. Nothing to install.
docapi_generate_pdf is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the docapi_generate_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 docapi_generate_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.
docapi_generate_pdf is provided by the Docapi MCP server (docapi/docapi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
