query_render_postgres
Run a read-only SQL query against a Render Postgres database
Part of the Render MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents invoke query_render_postgres to trigger processes or run actions in Render. Execute operations can have side effects beyond the immediate call — triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
WHY ENFORCE A POLICY ON QUERY_RENDER_POSTGRES
query_render_postgres can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.
RECOMMENDED POLICY
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

FREQUENTLY ASKED QUESTIONS
What does the query_render_postgres tool do?
Run a read-only SQL query against a Render Postgres database. It is categorised as a Execute tool in the Render MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
How do I enforce a policy on query_render_postgres?
Add a rule in your Intercept YAML policy under the tools section for query_render_postgres. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Render MCP server.
What risk level is query_render_postgres?
query_render_postgres is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Can I rate-limit query_render_postgres?
Yes. Add a rate_limit block to the query_render_postgres rule in your Intercept 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.
How do I block query_render_postgres completely?
Set action: deny in the Intercept policy for query_render_postgres. 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.
What MCP server provides query_render_postgres?
query_render_postgres is provided by the Render MCP server (render-oss/render-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
