Return the Profit & Loss statement for a business entity for a given
AI agents call get_pnl to retrieve information from Luni MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Despite being financial data with significant sensitivity (P&L statements are confidential business information), the tool only retrieves/queries existing data without side effects. It does not execute transactions, modify records, or delete data.
From the tool's definition Tool name 'get_pnl' and description indicate retrieval ('Return') of financial data; no modification or deletion capability is described. The description explicitly states it returns a 'Profit & Loss statement', which is a read operation.

Register the Luni MCP Server MCP server in PolicyLayer and add a rule for get_pnl: 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 Luni MCP Server. Nothing to install.
get_pnl 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 get_pnl 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 get_pnl. 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.
get_pnl is provided by the Luni MCP Server MCP server (rorygeddes/luni_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
