AI agents call check_cli_status to retrieve information from Review MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries system state to determine which review CLIs are available. It retrieves information without creating, modifying, deleting, or executing code. No reversible or irreversible changes occur, and no external operations are triggered. This is a straightforward diagnostic read operation.
From the tool's definition Tool checks status of installed CLIs and reports availability; name 'check_cli_status' indicates diagnostic/information retrieval with no modifications or side effects.

Check which code review CLIs (Codex/OpenAI and Gemini) are installed and available. Use this before requesting reviews to see what. It is categorised as a Read tool in the Review MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Review MCP Server MCP server in PolicyLayer and add a rule for check_cli_status: 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 Review MCP Server. Nothing to install.
check_cli_status is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the check_cli_status 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 check_cli_status. 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.
check_cli_status is provided by the Review MCP Server MCP server (je4550/review-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
