WHAT IT DOES

What list_partitions does on Mcpg

AI agents call list_partitions to retrieve information from Mcpg without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_partitions is rated Low

The tool lists existing partitions, which is a read-only query operation. The lack of description lowers confidence slightly, but the naming convention 'list_*' strongly suggests data retrieval with no side effects. No write, destructive, execute, or financial operations are indicated.

From the tool's definition Tool name 'list_partitions' indicates a retrieval operation that queries partition metadata from a PostgreSQL database without modifying or deleting data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_partitions safely

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

list_partitions Allowed

list_partitions is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_partitions": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcpg, apply this rule, and every list_partitions call is checked against it from then on.
