What install_template_library does on Todos
AI agents use install_template_library 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 install_template_library is rated Medium
This tool creates or populates template records in a local database. While installation is generally reversible and idempotent, it modifies local state and could introduce unwanted templates or overwrite existing configurations if triggered unexpectedly by an agent. This makes it Write rather than Execute (no arbitrary code/commands) or Destructive (idempotent nature suggests reversibility).
From the tool's definition Tool description states 'Install all bundled templates into local database' - the verb 'install' combined with 'into local database' indicates data creation/modification.
Attacks that exploit this kind of access
The rule that runs install_template_library 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 install_template_library, this is the rule to start with:
install_template_library 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 install_template_library call is checked against it from then on.
