create_pbi · Vacklogen MCP: Risk & Policy

WHAT IT DOES

What create_pbi does on Vacklogen

AI agents use create_pbi to create or update resources in Vacklogen — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Vacklogen environment.

WHY IT NEEDS A POLICY

Why create_pbi needs a policy

This tool creates new Product Backlog Item (PBI) entries, which is a data modification operation. It is reversible (can be deleted) and has a bounded scope (adding to a specific project), making it Write category rather than Execute or Destructive. Severity is medium because creating unwanted PBIs could clutter a project backlog and require cleanup, but the impact is contained and reversible.

From the tool's definition Tool name 'create_pbi' and description 'Add a new PBI as a stub to an existing project' indicate creation of new data.

Verdict

create_pbi Rate-limited

create_pbi 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.
