WHAT IT DOES

What create_object_storage_key does on Linode MCP Server

AI agents use create_object_storage_key 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 create_object_storage_key is rated Medium

This tool creates new API credentials for Object Storage access. While creation is technically reversible (keys can be revoked), the tool generates secrets that permanently authorize access to storage until explicitly deleted. Misuse allows an AI agent to create persistent backdoor credentials, establish unauthorized access to object storage, or elevate privileges.

From the tool's definition Tool name 'create_object_storage_key' and description 'Create a new Object Storage key' indicate irreversible creation of credentials that grant access to cloud storage resources.

RECOMMENDED RULE

The rule that runs create_object_storage_key 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 create_object_storage_key, this is the rule to start with:

create_object_storage_key Rate-limited

create_object_storage_key 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.
