// WHEN AI AGENTS USE THIS TOOL

AI agents invoke debugger_step_out to trigger processes or run actions in Mcp Debugger. 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 DEBUGGER_STEP_OUT

debugger_step_out 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 debugger_step_out tool do? +

Execute until the current function returns and pause at the calling location.. It is categorised as a Execute tool in the Mcp Debugger MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on debugger_step_out? +

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

What risk level is debugger_step_out? +

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

Can I rate-limit debugger_step_out? +

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

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

debugger_step_out is provided by the Mcp Debugger MCP server (@ai-capabilities-suite/mcp-debugger-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
