Check all sessions for interactive prompts that need user attention.
AI agents call check_prompts to retrieve information from Claude Code MCP Controller without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves status information about pending prompts across sessions without modifying, executing, or deleting anything. It is informational/observational in nature. Low severity because the information disclosed (pending prompts) is unlikely to cause substantial harm even if misused by an agent, though it could reveal sensitive context from user interactions.
From the tool's definition Tool name 'check_prompts' and description 'Check all sessions for interactive prompts that need user attention' indicate a query/monitoring operation with no side effects.

Yes. Add a rate_limit block to the check_prompts 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_prompts. 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_prompts is provided by the Claude Code MCP Controller MCP server (mostafa-drz/claude-code-mcp-controller). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
