What create_manual_checkpoint does on Todos
AI agents use create_manual_checkpoint to create or update resources in Todos, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Todos environment.
Why create_manual_checkpoint is rated Medium
This tool creates new checkpoint records, which is a Write operation (creates data reversibly). It's not Read (doesn't just query), not Execute (doesn't run external code or shell commands), not Destructive (checkpoints can be removed/superseded), and not Financial.
From the tool's definition Tool name 'create_manual_checkpoint' and description 'Create a manual checkpoint on a task' indicates creating/persisting new checkpoint data on an existing task. The mention of 'optionally requiring approval' suggests this modifies task state.
Attacks that exploit this kind of access
The rule that runs create_manual_checkpoint safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Todos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_manual_checkpoint, this is the rule to start with:
create_manual_checkpoint stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Todos, apply this rule, and every create_manual_checkpoint call is checked against it from then on.
