// WHEN AI AGENTS USE THIS TOOL

AI agents invoke execute_r_async to trigger processes or run actions in ClaudeR - RStudio MCP Server. 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 EXECUTE_R_ASYNC

execute_r_async 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 execute_r_async tool do? +

Run long-running R code in background. It is categorised as a Execute tool in the ClaudeR - RStudio MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on execute_r_async? +

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

What risk level is execute_r_async? +

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

Can I rate-limit execute_r_async? +

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

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

execute_r_async is provided by the ClaudeR - RStudio MCP Server MCP server (clauder-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
