AI agents call diagnose_workbook to retrieve information from ModelRisk MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Without explicit description, the name 'diagnose_workbook' most naturally implies introspection or analysis of a workbook's structure and state—a read-only operation. The empty description lowers confidence slightly, but the presence of parallel read tools on the server and the diagnostic naming pattern support a Read classification.

diagnose_workbook. It is categorised as a Read tool in the ModelRisk MCP MCP Server, which means it retrieves data without modifying state.
Register the ModelRisk MCP server in PolicyLayer and add a rule for diagnose_workbook: 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 ModelRisk MCP. Nothing to install.
diagnose_workbook 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 diagnose_workbook 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 diagnose_workbook. 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.
diagnose_workbook is provided by the ModelRisk MCP server (vosesoftware/modelrisk-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
