What SelectWorktree does on DutyDeck
AI agents use SelectWorktree to create or update resources in DutyDeck, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DutyDeck environment.
Why SelectWorktree is rated Medium
An AI agent can call SelectWorktree faster than any human can review: one bad instruction and it creates or modifies resources in DutyDeck by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs SelectWorktree safely
PolicyLayer is an MCP gateway: it sits between your AI agents and DutyDeck, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For SelectWorktree, this is the rule to start with:
SelectWorktree 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 DutyDeck, apply this rule, and every SelectWorktree call is checked against it from then on.
Questions about SelectWorktree
Bind this Agent session to an existing linked Git worktree that belongs to an authorized or registered repository. Use immediately after creating or identifying the worktree, before editing its files. The binding updates the visible Changes tab now and makes the worktree the Agent cwd for subsequent runs. It is categorised as a Write tool in the DutyDeck MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the DutyDeck MCP server in PolicyLayer and add a rule for SelectWorktree: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches DutyDeck. Nothing to install.
SelectWorktree is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the SelectWorktree rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for SelectWorktree. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
SelectWorktree is provided by the DutyDeck MCP server (taokoplay/DutyDeck). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
