THE RISK

Critical Risk

Why delete_postgresql_connection_pool needs a policy

Deleting a connection pool is an irreversible action that removes database connectivity infrastructure. While not as severe as deleting the database itself, it can cause application outages and cannot be undone without manual reconfiguration. This fits the Destructive category as it removes data/configuration that cannot be automatically recovered.

From the tool's definition Tool name contains 'delete' and description states 'Delete a connection pool from a PostgreSQL database instance' - this irreversibly removes database infrastructure configuration.

POLICY

How to control delete_postgresql_connection_pool

PolicyLayer is an MCP gateway — it sits between your AI agents and Linode MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_postgresql_connection_pool:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_postgresql_connection_pool"
  ]
}

delete_postgresql_connection_pool disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Linode MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
