Apply query tuning optimisations

Modifies database configuration

Part of the Neon MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents use complete_query_tuning to create or modify resources in Neon. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call complete_query_tuning repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Neon.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the complete_query_tuning tool do? +

Apply query tuning optimisations. It is categorised as a Write tool in the Neon MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on complete_query_tuning? +

Add a rule in your Intercept YAML policy under the tools section for complete_query_tuning. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Neon MCP server.

What risk level is complete_query_tuning? +

complete_query_tuning is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit complete_query_tuning? +

Yes. Add a rate_limit block to the complete_query_tuning 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 complete_query_tuning completely? +

Set action: deny in the Intercept policy for complete_query_tuning. 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 complete_query_tuning? +

complete_query_tuning is provided by the Neon MCP server (@neondatabase/mcp-server-neon). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
