WHAT IT DOES

What add_nodebalancer_config does on Linode MCP Server

AI agents use add_nodebalancer_config 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 add_nodebalancer_config is rated Medium

This tool creates or modifies NodeBalancer port configurations, which is a reversible operation that changes infrastructure state but does not delete data or execute arbitrary code. It falls under Write category. Severity is medium because misconfiguration could route traffic incorrectly or cause service disruption, but the change can be undone by modifying or removing the configuration.

From the tool's definition Tool name 'add_nodebalancer_config' with description 'Add a port configuration to a NodeBalancer' indicates creating/modifying load balancer configuration settings.

RECOMMENDED RULE

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

add_nodebalancer_config Rate-limited

add_nodebalancer_config 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 Linode MCP Server, apply this rule, and every add_nodebalancer_config call is checked against it from then on.
