create_state · Plane MCP: Risk & Policy

WHAT IT DOES

What create_state does on Plane

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

WHY IT NEEDS A POLICY

Why create_state needs a policy

The 'create_' prefix strongly suggests this tool creates or adds a new state (likely a workflow state, status, or project state) in the Plane system. This is a reversible Write operation—states can typically be modified or deleted later.

From the tool's definition Tool name is 'create_state' and is on a project management/work item tracking server (Plane). The 'create_' prefix indicates data creation. Description is empty, limiting certainty.

Verdict

create_state Rate-limited

create_state 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.

FAQ

Questions about create_state

What does the create_state tool do? +

create_state. It is categorised as a Write tool in the Plane MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_state? +

Register the Plane MCP server in PolicyLayer and add a rule for create_state: 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 Plane. Nothing to install.

What risk level is create_state? +

create_state is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_state? +

Yes. Add a rate_limit block to the create_state 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.

How do I block create_state completely? +

Set action: deny in the PolicyLayer policy for create_state. 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.

What MCP server provides create_state? +

create_state is provided by the Plane MCP server (@makeplane/plane-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
