AI agents use create_workspace to create or update resources in Smartsheet MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Smartsheet MCP Server environment.
This tool creates a new resource (workspace) in Smartsheet, which is a reversible Write operation. The user can delete or modify the workspace afterward. While it establishes a new container for collaboration, it does not execute arbitrary code, delete data irreversibly, or commit financial obligations.
From the tool's definition Tool name 'create_workspace' and description 'Create a new workspace' indicate creation of a new organizational container within Smartsheet.
Documented attack patterns abuse exactly the kind of access create_workspace gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Smartsheet MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_workspace:
{
"version": "1",
"default": "deny",
"tools": {
"create_workspace": {
"limits": [
{
"counter": "create_workspace_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}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.
Free to start. No card required.
Create a new workspace. It is categorised as a Write tool in the Smartsheet MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Smartsheet MCP Server 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 Smartsheet MCP Server. 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 Smartsheet MCP Server MCP server (terilios/smartsheet-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Smartsheet MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
