node-server-orchestrator Execute Risk 5/5

// WHEN AI AGENTS USE THIS TOOL

AI agents invoke command to trigger processes or run actions in Node Server Orchestrator. 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 COMMAND

command 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 command tool do? +

Configure startup command for a server. It is categorised as a Execute tool in the Node Server Orchestrator MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on command? +

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

What risk level is command? +

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

Can I rate-limit command? +

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

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

command is provided by the Node Server Orchestrator MCP server (node-server-orchestrator). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
