WHAT IT DOES

What blur_gaussian does on farshid-mcp-imageProcessing

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

WHY IT NEEDS A POLICY

Why blur_gaussian needs a policy

This tool modifies image data by applying a Gaussian blur filter. It creates a transformed version of the image, which is a reversible write/modification operation. It does not delete data, execute arbitrary code, or involve financial transactions. Severity is low as it only affects image processing outputs.

From the tool's definition Apply Gaussian blur. ksize is forced to odd.

Verdict

blur_gaussian Rate-limited

blur_gaussian 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches farshid-mcp-imageProcessing, so you can run agents against it safely.

FAQ

Questions about blur_gaussian

What does the blur_gaussian tool do? +

Apply Gaussian blur. ksize is forced to odd. It is categorised as a Write tool in the farshid-mcp-imageProcessing MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on blur_gaussian? +

Register the farshid-mcp-imageProcessing MCP server in PolicyLayer and add a rule for blur_gaussian: 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 farshid-mcp-imageProcessing. Nothing to install.

What risk level is blur_gaussian? +

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

Can I rate-limit blur_gaussian? +

Yes. Add a rate_limit block to the blur_gaussian 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.

How do I block blur_gaussian completely? +

Set action: deny in the PolicyLayer policy for blur_gaussian. 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 blur_gaussian? +

blur_gaussian is provided by the farshid-mcp-imageProcessing MCP server (pirahansiah/farshid-mcp-imageprocessing). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
