What set_workspace_trust does on Todos
AI agents use set_workspace_trust 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 set_workspace_trust is rated Medium
This tool modifies security-relevant configuration (workspace trust/permissions) but does so reversibly. It's a Write operation rather than Execute because it doesn't run arbitrary code or trigger external operations—it configures access control. The 'medium' severity reflects that misconfiguration could grant unintended permissions, affecting multiple tasks or users in the workspace, but changes can be reverted.
From the tool's definition Tool name is 'set_workspace_trust' and description states it will 'Create or update a local workspace trust and permission profile.' The verbs 'create' and 'update' indicate reversible data modification.
Attacks that exploit this kind of access
The rule that runs set_workspace_trust 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 set_workspace_trust, this is the rule to start with:
set_workspace_trust 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 set_workspace_trust call is checked against it from then on.
