// MCP TOOL REFERENCE

gemini_run_code

Execute Python code via Gemini sandbox

Runs arbitrary Python code remotely

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

// WHEN AI AGENTS USE THIS TOOL

AI agents invoke gemini_run_code to trigger processes or run actions in MCP Gemini. 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 GEMINI_RUN_CODE

gemini_run_code 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.

mcp-gemini.yaml

tools:
  gemini_run_code:
    rules:
      - action: allow
        rate_limit:
          max: 10
          window: 60
        validate:
          required_args: true

// FAQ

What does the gemini_run_code tool do? +

Execute Python code via Gemini sandbox. It is categorised as a Execute tool in the MCP Gemini MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on gemini_run_code? +

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

What risk level is gemini_run_code? +

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

Can I rate-limit gemini_run_code? +

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

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

gemini_run_code is provided by the MCP Gemini MCP server (mcp-gemini-crunchtools). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
