WHAT IT DOES

What create_milestone does on Todos

AI agents use create_milestone 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.

RISK

Why create_milestone is rated Medium

This tool creates a new milestone entity in a task management system. It modifies the roadmap data structure by adding a new element, which is a reversible write operation. The blast radius is medium because adding a milestone could affect project planning and team coordination, but the operation is not destructive (can be removed) and does not involve financial transactions or code execution.

From the tool's definition Tool description states 'Add a local milestone to a roadmap.' The verb 'Add' indicates creation of new data (a milestone) that is reversible through standard update/delete operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_milestone 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_milestone, this is the rule to start with:

create_milestone Rate-limited

create_milestone 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_milestone call is checked against it from then on.
