WHAT IT DOES

What grok does on Deliberation

AI agents invoke grok to trigger actions in Deliberation. 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.

RISK

Why grok is rated High

While labeled 'Advisory only (no filesystem editing)', initiating a session with an external LLM service and attaching files to that session triggers external processing. This is an Execute-category action because it runs a remote operation (Grok inference) whose outputs and side effects (API calls, quota consumption, potential information disclosure from attached files) depend on the provided arguments.

From the tool's definition Tool description states 'Start a new Grok (xAI) expert session' and 'Supports attaching files'. The ability to initiate external API calls to Grok (xAI's language model) and attach arbitrary files constitutes execution of an external operation whose effects…

RECOMMENDED RULE

The rule that runs grok safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Deliberation, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For grok, this is the rule to start with:

grok Rate-limited

grok 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.

          "max": 10,

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Deliberation, apply this rule, and every grok call is checked against it from then on.

FAQ

Questions about grok

What does the grok tool do? +

Start a new Grok (xAI) expert session. Advisory only (no filesystem editing). Supports attaching files. It is categorised as a Execute tool in the Deliberation MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on grok? +

Register the Deliberation MCP server in PolicyLayer and add a rule for grok: 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 Deliberation. Nothing to install.

What risk level is grok? +

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

Can I rate-limit grok? +

Yes. Add a rate_limit block to the grok 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.

How do I block grok completely? +

Set action: deny in the PolicyLayer policy for grok. 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 grok? +

grok is provided by the Deliberation MCP server (antonbabenko/deliberation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
