Get important PostgreSQL configuration parameters and their current values.
AI agents call PostgreSQL_get_important_settings to retrieve information from Postgres without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays PostgreSQL configuration data with no side effects. It is a read-only operation that gathers diagnostic information about database settings. While exposure of certain configuration details (e.g., credentials, paths) could inform a subsequent attack, the tool itself performs no destructive, write, financial, or code execution action.
From the tool's definition Tool name and description indicate retrieval of configuration parameters: 'Get important PostgreSQL configuration parameters and their current values.' The action is purely informational—querying existing settings without modification, deletion, or execution…
Documented attack patterns abuse exactly the kind of access PostgreSQL_get_important_settings gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Postgres, and nothing reaches the server without passing your rules. This is the rule we recommend for PostgreSQL_get_important_settings:
{
"version": "1",
"default": "deny",
"tools": {
"PostgreSQL_get_important_settings": {}
}
}PostgreSQL_get_important_settings is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get important PostgreSQL configuration parameters and their current values. It is categorised as a Read tool in the Postgres MCP Server, which means it retrieves data without modifying state.
Register the Postgres MCP server in PolicyLayer and add a rule for PostgreSQL_get_important_settings: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Postgres. Nothing to install.
PostgreSQL_get_important_settings is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the PostgreSQL_get_important_settings rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for PostgreSQL_get_important_settings. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
PostgreSQL_get_important_settings is provided by the Postgres MCP server (mukul975/postgres-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Postgres, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
