AI agents call get_organization to retrieve information from PostgREST without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves organization details without modifying, deleting, or executing any operations. It is a read-only query operation. The severity is low because organization metadata typically has limited sensitivity and no blast radius for misuse beyond information disclosure. The confidence is high because the name and description clearly indicate a simple data retrieval function.
From the tool's definition Tool name 'get_organization' and description 'Gets details for an organization' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_organization gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PostgREST, and nothing reaches the server without passing your rules. This is the rule we recommend for get_organization:
{
"version": "1",
"default": "deny",
"tools": {
"get_organization": {}
}
}get_organization is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Gets details for an organization. It is categorised as a Read tool in the PostgREST MCP Server, which means it retrieves data without modifying state.
Register the PostgREST MCP server in PolicyLayer and add a rule for get_organization: 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 PostgREST. Nothing to install.
get_organization 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 get_organization 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 get_organization. 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.
get_organization is provided by the PostgREST MCP server (supabase/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
