List bill runs. GET /bill-run. Optional: include (e.g. invoice), query (filter by status: completed, pending, error), orderBy, sortBy, itemPerPage, pageNo.
AI agents call list_bill_runs to retrieve information from Rebillia MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves billing run data without modifying, deleting, or executing operations. It supports standard read-only operations like filtering (status), ordering, and pagination. No side effects or state changes occur. Severity is low because reading billing data poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'list_bill_runs' and description 'List bill runs' with GET /bill-run endpoint and optional filtering/sorting parameters indicate data retrieval only.

Register the Rebillia MCP Server MCP server in PolicyLayer and add a rule for list_bill_runs: 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 Rebillia MCP Server. Nothing to install.
list_bill_runs 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_bill_runs 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_bill_runs. 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.
