WHAT IT DOES

What plan_agent_branches does on Mcp Control Plane

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

RISK

Why plan_agent_branches is rated Medium

The tool creates (writes) branch manifests that define how parallel agents will execute. This is reversible configuration creation—manifests can be modified or deleted, and the tool itself doesn't execute arbitrary code or make destructive/financial changes.

From the tool's definition Tool name 'plan_agent_branches' and description 'Create branch manifests for parallel Codex agents' indicate creation of configuration/manifest data that directs agent execution behavior.

RECOMMENDED RULE

The rule that runs plan_agent_branches safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Control Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For plan_agent_branches, this is the rule to start with:

plan_agent_branches Rate-limited

plan_agent_branches 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.
