Why partition_strategy_suggest needs a policy

The tool performs analysis and querying of database schema/statistics to provide suggestions. It retrieves data about tables to generate recommendations but does not create, modify, delete, or execute any changes. This is a read-only advisory operation with no side effects on the database state.

From the tool's definition Tool name 'partition_strategy_suggest' and description 'Suggest partitioning strategy for large tables' indicate the tool analyzes and recommends strategies without executing any modifications, deletions, or external operations.

POLICY

How to control partition_strategy_suggest

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

policy.json

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

partition_strategy_suggest is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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