List Franchise Business Unit records. An FBU is one operational unit (one brand × one market under one franchisee). Filters: franchisee, brand, status.
AI agents call list_fbus to retrieve information from Frappe MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and filters existing data (FBU records) without creating, modifying, deleting, or executing operations. It is a straightforward query operation consistent with the Read category. The read-only server designation and the absence of any mutative language confirm low severity.
From the tool's definition Tool description states 'List Franchise Business Unit records' with filters for franchisee, brand, and status. The server is explicitly described as 'Read-only MCP server' that enables agents to 'query' data.

Register the Frappe MCP server in PolicyLayer and add a rule for list_fbus: 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 Frappe MCP. Nothing to install.
list_fbus 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 list_fbus 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 list_fbus. 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.
