add_project · Quarterback MCP: Risk & Policy

WHAT IT DOES

What add_project does on Quarterback

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

WHY IT NEEDS A POLICY

Why add_project needs a policy

The tool creates a new project record, which is a reversible write operation. It modifies the system state by adding data rather than executing arbitrary code or deleting data. Severity is medium because adding a project could trigger downstream workflows or allocate resources, but the action itself is not irreversible and the blast radius depends on what the newly created project contains.

From the tool's definition Tool name is 'add_project' and description states 'Add a new project' - this creates new data in the system.

Verdict

add_project Rate-limited

add_project 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.
