Writes PDF file to filesystem
Part of the Playwright MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use browser_pdf_save to create or modify resources in Playwright. 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 browser_pdf_save repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Playwright.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Agents calling write-class tools like browser_pdf_save have been implicated in these attack patterns. Read the full case and prevention policy for each:
Other tools in the Write risk category across the catalogue. The same policy patterns (rate-limit, validate) apply to each.
Save the current page as a PDF file. It is categorised as a Write tool in the Playwright MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Add a rule in your Intercept YAML policy under the tools section for browser_pdf_save. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Playwright MCP server.
browser_pdf_save 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 browser_pdf_save 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 browser_pdf_save. 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.
browser_pdf_save is provided by the Playwright MCP server (@microsoft/playwright-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
