extract_postgresql_content
AI agents call extract_postgresql_content to retrieve information from Allcanuse without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears designed to retrieve or query PostgreSQL data with no side effects mentioned. However, confidence is moderate (0.7) because the description is empty and 'extract' could potentially involve exporting sensitive data at scale.
From the tool's definition Tool name 'extract_postgresql_content' indicates data retrieval from a PostgreSQL database. No description provided, but the verb 'extract' and reference to 'content' suggest read-only querying.

PolicyLayer is an MCP gateway — it sits between your AI agents and Allcanuse, and nothing reaches the server without passing your rules. This is the rule we recommend for extract_postgresql_content:
{
"version": "1",
"default": "deny",
"tools": {
"extract_postgresql_content": {}
}
}extract_postgresql_content is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Start from Allcanuse, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
