AI agents call todos_retro 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 retrieves and queries retrospective data about task completion metrics. It performs analysis and reporting on existing data without creating, modifying, deleting, or executing external operations. The task management context and sibling tools (like add_task_*, acquire_task_lease) confirm this is a read-only analytics/reporting feature.
From the tool's definition Tool provides 'stats on completed tasks, low-confidence completions, avg time vs estimate, and patterns' — purely analytical/reporting functions with no modification or deletion of data.
Attacks that exploit this kind of access
Post-completion retrospective: stats on completed tasks, low-confidence completions, avg time vs estimate, and patterns. It is categorised as a Read tool in the Todos MCP Server, which means it retrieves data without modifying state.
Register the Todos MCP server in PolicyLayer and add a rule for todos_retro: 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 Todos. Nothing to install.
todos_retro 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 todos_retro 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 todos_retro. 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.
