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

@niledatabase/nile-mcp-server Destructive Risk 4/5

// WHEN AI AGENTS USE THIS TOOL

AI agents may call Example to permanently remove or destroy resources in Nile. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.

// WHY ENFORCE A POLICY ON EXAMPLE

Without a policy, an AI agent could call Example in a loop, permanently destroying resources in Nile. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

// RECOMMENDED POLICY

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

nile.yaml

tools:
  Example:
    rules:
      - action: deny
        reason: "Blocked by default — enable with approval"

What does the Example tool do? +

"Delete tenant named 'acme-corp' in my-app". It is categorised as a Destructive tool in the Nile MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on Example? +

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

What risk level is Example? +

Example is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit Example? +

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

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

Example is provided by the Nile MCP server (@niledatabase/nile-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
