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

// WHEN AI AGENTS USE THIS TOOL

AI agents invoke pihole_update_gravity to trigger processes or run actions in Mcp Pihole. 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 PIHOLE_UPDATE_GRAVITY

pihole_update_gravity 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.

// FAQ

What does the pihole_update_gravity tool do? +

Update Pi-hole blocklists from sources. It is categorised as a Execute tool in the Mcp Pihole MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on pihole_update_gravity? +

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

What risk level is pihole_update_gravity? +

pihole_update_gravity is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit pihole_update_gravity? +

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

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

pihole_update_gravity is provided by the Mcp Pihole MCP server (mcp-pihole-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
