AI agents use upload_complete to create or modify resources in SlideMaster. 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 upload_complete 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 SlideMaster.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access upload_complete gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Use this after the file has been uploaded to the pre-signed URL. Triggers server-side processing.. It is categorised as a Write tool in the SlideMaster MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the SlideMaster MCP server in PolicyLayer and add a rule for upload_complete: 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 SlideMaster. Nothing to install.
upload_complete 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 upload_complete 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 upload_complete. 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.
upload_complete is provided by the SlideMaster MCP server (@slidemaster/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
