List all starter workspaces accessible to the user
AI agents call list_starter_workspaces to retrieve information from SingleStore MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about starter workspaces without modifying, deleting, or executing any operations. It is a simple data retrieval function with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name includes 'list' and description states 'List all starter workspaces accessible to the user' — a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_starter_workspaces gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and SingleStore MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_starter_workspaces:
{
"version": "1",
"default": "deny",
"tools": {
"list_starter_workspaces": {}
}
}list_starter_workspaces is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all starter workspaces accessible to the user. It is categorised as a Read tool in the SingleStore MCP Server MCP Server, which means it retrieves data without modifying state.
Register the SingleStore MCP Server MCP server in PolicyLayer and add a rule for list_starter_workspaces: 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 SingleStore MCP Server. Nothing to install.
list_starter_workspaces is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_starter_workspaces 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 list_starter_workspaces. 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.
list_starter_workspaces is provided by the SingleStore MCP Server MCP server (singlestore-labs/mcp-server-singlestore). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
