Searches the Supabase documentation for up-to-date information. LLMs can use this to find answers to questions or learn how to use specific features.
AI agents call search_docs 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 performs a search/query operation against documentation, returning information without modifying, deleting, or executing any code or operations. It is a pure read operation with minimal blast radius—an AI agent cannot misuse it to cause data loss, financial harm, or unintended system changes.
From the tool's definition Tool name 'search_docs' and description 'Searches the Supabase documentation for up-to-date information' indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access search_docs 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 search_docs:
{
"version": "1",
"default": "deny",
"tools": {
"search_docs": {}
}
}search_docs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Searches the Supabase documentation for up-to-date information. LLMs can use this to find answers to questions or learn how to use specific features. 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 search_docs: 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.
search_docs 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 search_docs 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 search_docs. 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.
search_docs 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.
