Create a new workspace in the organization
AI agents use claude_code_create_workspace to create or update resources in Sage MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sage MCP environment.
This tool creates a new organizational workspace, which is a write operation that modifies the state of the system by adding a new resource. While workspaces are typically reversible (can be deleted), the creation establishes new infrastructure/configuration that other users may depend on.
From the tool's definition Tool name contains 'create' and description states 'Create a new workspace in the organization', indicating it creates a new resource (workspace) with side effects that are reversible.
Documented attack patterns abuse exactly the kind of access claude_code_create_workspace gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for claude_code_create_workspace:
{
"version": "1",
"default": "deny",
"tools": {
"claude_code_create_workspace": {
"limits": [
{
"counter": "claude_code_create_workspace_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}claude_code_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.

Create a new workspace in the organization. It is categorised as a Write tool in the Sage MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sage MCP server in PolicyLayer and add a rule for claude_code_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 Sage MCP. Nothing to install.
claude_code_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 claude_code_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 claude_code_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.
claude_code_create_workspace is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
