Check Pre-RC research progress. Read-only, safe to call anytime. Returns: current stage, completed stages, gate statuses, persona results, token usage. Use this to orient yourself when resuming a session or when the user asks
AI agents call prc_status to retrieve information from RC Engine without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries pipeline status information with no side effects or data modifications. It is clearly a read-only diagnostic tool designed for orientation and monitoring, fitting the Read category definition of 'retrieves or queries data; no side effects'.
From the tool's definition Tool description explicitly states 'Read-only, safe to call anytime' and 'Returns: current stage, completed stages, gate statuses, persona results, token usage.' It retrieves status information without modifying any data.

Check Pre-RC research progress. Read-only, safe to call anytime. Returns: current stage, completed stages, gate statuses, persona results, token usage. Use this to orient yourself when resuming a session or when the user asks. It is categorised as a Read tool in the RC Engine MCP Server, which means it retrieves data without modifying state.
Register the RC Engine MCP server in PolicyLayer and add a rule for prc_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 RC Engine. Nothing to install.
prc_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 prc_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 prc_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.
prc_status is provided by the RC Engine MCP server (originalrashmi/rc-engine-product-framework). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
