Medium Risk

split_pdf

Split a PDF into multiple PDFs by page ranges (e.g. "1-3,5-7") or into fixed-size chunks. Returns a .zip archive containing the resulting PDFs.

Part of the Pdf Toolkit MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

pdf-toolkit-mcp Write Risk 2/5

AI agents use split_pdf to create or modify resources in Pdf Toolkit. 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 split_pdf 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 Pdf Toolkit.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the split_pdf tool do? +

Split a PDF into multiple PDFs by page ranges (e.g. "1-3,5-7") or into fixed-size chunks. Returns a .zip archive containing the resulting PDFs.. It is categorised as a Write tool in the Pdf Toolkit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on split_pdf? +

Add a rule in your Intercept YAML policy under the tools section for split_pdf. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Pdf Toolkit MCP server.

What risk level is split_pdf? +

split_pdf is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit split_pdf? +

Yes. Add a rate_limit block to the split_pdf 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.

How do I block split_pdf completely? +

Set action: deny in the Intercept policy for split_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.

What MCP server provides split_pdf? +

split_pdf is provided by the Pdf Toolkit MCP server (pdf-toolkit-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
