What grok-reply does on Deliberation
AI agents invoke grok-reply 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.
Why grok-reply is rated High
This tool executes operations against the Grok service (a third-party LLM) by continuing a session. While it doesn't directly run shell commands or arbitrary code locally, it triggers external execution of AI model inference which can produce arbitrary outputs and side effects depending on the prior session context and new prompts. The in-memory session state means effects persist across calls.
From the tool's definition Tool continues an existing Grok session, implying execution of code or queries in an external model service. The session is in-memory and persists state across invocations, indicating stateful execution of generative AI model outputs.
Attacks that exploit this kind of access
The rule that runs grok-reply 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-reply, this is the rule to start with:
grok-reply 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Deliberation, apply this rule, and every grok-reply call is checked against it from then on.
Questions about grok-reply
Continue an existing Grok session (in-memory; lost if the MCP server restarts). 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.
Register the Deliberation MCP server in PolicyLayer and add a rule for grok-reply: 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.
grok-reply 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 grok-reply 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 grok-reply. 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.
grok-reply 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.
