WHAT IT DOES

What save_command_alias does on Todos

AI agents use save_command_alias 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 save_command_alias is rated Medium

This tool creates or modifies command aliases in project-local configuration, making it a reversible Write operation. While command aliases could potentially be misused to obfuscate malicious commands, the core action is configuration modification, not execution or deletion.

From the tool's definition Tool name explicitly states 'save' and description confirms 'Save or update', which are Write operations that create or modify data. The alias configuration is reversible and can be updated or removed later.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

save_command_alias Rate-limited

save_command_alias 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 save_command_alias call is checked against it from then on.
