pitch_upload_file · Llama MCP: Risk & Policy

WHAT IT DOES

What pitch_upload_file does on Llama

AI agents use pitch_upload_file to create or update resources in Llama — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Llama environment.

WHY IT NEEDS A POLICY

Why pitch_upload_file needs a policy

Uploading files creates new data or modifies existing pitch records on the platform. This is a Write operation (reversible via deletion) rather than Read (passive retrieval) or Destructive (irreversible). Severity is medium because file uploads could introduce malicious content or clutter if misused by an agent, but impact is limited to a single pitch and can be undone.

From the tool's definition Tool name 'pitch_upload_file' and description 'Attach a file... to the' indicate file creation/modification action on the Llama Ventures platform. The description is incomplete (cuts off mid-sentence), but the intent to attach/upload files is clear.
