Why mysql_show_replication_status needs a policy

This tool queries replication status metadata—a read-only monitoring operation. The description explicitly states it 'shows' status rather than modifying, executing, or deleting anything. Even though the server description mentions 'secure HTTP endpoints for read-only queries', this tool fits the Read category: it retrieves operational data with no side effects.

From the tool's definition Tool name 'show_replication_status' and description 'Show replication status including master and slave' indicate a query/monitoring operation that retrieves status information without modifying data or executing arbitrary commands.

POLICY

How to control mysql_show_replication_status

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

policy.json

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

mysql_show_replication_status 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 Mysql — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
