AI agents call list_audit_ledger_checkpoints to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation that retrieves audit ledger checkpoint information. There are no side effects, no data modification, no code execution, and no destructive operations. The sealed nature of the checkpoints confirms they cannot be modified through this listing operation. Severity is low as reading audit logs presents minimal risk even if misused by an AI agent.
From the tool's definition Tool name contains 'list' and description states 'List sealed local audit ledger checkpoints' — retrieves/queries audit checkpoint data without modification. The 'sealed' qualifier indicates read-only access to immutable records.

list_audit_ledger_checkpoints 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_audit_ledger_checkpoints 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_audit_ledger_checkpoints. 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.
list_audit_ledger_checkpoints is provided by the Todos MCP server (@hasna/todos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_audit_ledger_checkpoints is one line of Todos's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
