WHAT IT DOES

What upload_image does on Linode MCP Server

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

RISK

Why upload_image is rated Medium

This tool creates new image resources in the Linode cloud infrastructure. While uploads are not instantaneous deletions and can be reversed, they do modify the user's cloud state by adding new resources.

From the tool's definition Tool named 'upload_image' with description 'Initiate an Image upload' performs a write operation that creates or modifies data (uploading a new image to Linode infrastructure). The action is reversible through deletion.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs upload_image safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Linode MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For upload_image, this is the rule to start with:

upload_image Rate-limited

upload_image 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.
