Execute JavaScript or Python code in an isolated sandbox. Use for: data processing, math, CSV parsing, JSON transformation, crypto calculations, algorithm testing. Secure — no filesystem access, no network. Returns: { output: string, runtime_ms: number, language: string }. Requires API key.
AI agents invoke x711_code_sandbox to trigger actions in X711io universal gas station market and intelligence. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
code | string | — | Code to execute. Examples: 'console.log(Math.sqrt(144))' or 'print(sum([1,2,3]))'. |
language | string | — | Language to run. Defaults to 'javascript'. |
Parameters from the server's own tool schema.
x711_code_sandbox triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

Documented attack patterns abuse exactly the kind of access x711_code_sandbox gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and X711io universal gas station market and intelligence, and nothing reaches the server without passing your rules. This is the rule we recommend for x711_code_sandbox:
{
"version": "1",
"default": "deny",
"tools": {
"x711_code_sandbox": {
"limits": [
{
"counter": "x711_code_sandbox_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}x711_code_sandbox stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Execute JavaScript or Python code in an isolated sandbox. Use for: data processing, math, CSV parsing, JSON transformation, crypto calculations, algorithm testing. Secure — no filesystem access, no network. Returns: { output: string, runtime_ms: number, language: string }. Requires API key. It is categorised as a Execute tool in the X711io universal gas station market and intelligence MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
x711_code_sandbox accepts 2 parameters: code, language. The full parameter table on this page comes from the server's own tool schema.
Register the X711io universal gas station market and intelligence MCP server in PolicyLayer and add a rule for x711_code_sandbox: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches X711io universal gas station market and intelligence. Nothing to install.
x711_code_sandbox is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the x711_code_sandbox rule in your PolicyLayer 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.
Set action: deny in the PolicyLayer policy for x711_code_sandbox. 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.
x711_code_sandbox is provided by the X711io universal gas station market and intelligence MCP server (ramboweb3/hivecast-x711). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
