What batch_image_process does on CoWork OS
AI agents use batch_image_process to create or update resources in CoWork OS, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CoWork OS environment.
Why batch_image_process is rated Medium
Batch image processing creates or modifies image files. While the operations (resize, format conversion, watermarking) are technically reversible or can be undone through subsequent processing, they alter user data in bulk. This is a Write operation rather than Read (only queries data), Execute (triggers code with unpredictable side effects), or Destructive (permanently deletes).
From the tool's definition Tool description states it can 'resize, convert format, and/or add a watermark/logo' to images—these are reversible modifications to files.

The rule that runs batch_image_process safely
PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For batch_image_process, this is the rule to start with:
batch_image_process stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect CoWork OS, apply this rule, and every batch_image_process call is checked against it from then on.
Questions about batch_image_process
Batch process multiple images: resize, convert format, and/or add a watermark/logo. It is categorised as a Write tool in the CoWork OS MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the CoWork OS MCP server in PolicyLayer and add a rule for batch_image_process: 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 CoWork OS. Nothing to install.
batch_image_process 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 batch_image_process 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 batch_image_process. 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.
batch_image_process is provided by the CoWork OS MCP server (CoWork-OS/CoWork-OS). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
