What create_workspace does on Ncp
AI agents use create_workspace to create or update resources in Ncp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ncp environment.
Why create_workspace is rated Medium
This tool creates new cloud infrastructure resources in Terraform Cloud (a state management and orchestration platform). Creation is reversible via deletion, distinguishing it from Destructive. It modifies the Terraform Cloud environment by adding a new workspace, making it Write rather than Read.
From the tool's definition Creates a Terraform Cloud workspace, which is a reversible resource creation operation. The tool instantiates new infrastructure configuration state/resources in Terraform Cloud.
Attacks that exploit this kind of access
The rule that runs create_workspace safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ncp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_workspace, this is the rule to start with:
create_workspace 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 Ncp, apply this rule, and every create_workspace call is checked against it from then on.
Questions about create_workspace
Create Terraform Cloud workspace. It is categorised as a Write tool in the Ncp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ncp MCP server in PolicyLayer and add a rule for create_workspace: 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 Ncp. Nothing to install.
create_workspace 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 create_workspace 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 create_workspace. 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.
create_workspace is provided by the Ncp MCP server (@portel/ncp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
