Retrieve details about the workspace groups accessible to the user
AI agents call workspace_groups_info 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 retrieves metadata about workspace groups that the user has access to. It performs no side effects, makes no modifications to data, executes no code, and poses minimal risk. The verb 'retrieve' and the passive nature of the operation clearly indicate a Read category classification.
From the tool's definition Tool name 'workspace_groups_info' and description 'Retrieve details about the workspace groups accessible to the user' indicate a read-only operation that queries and returns information without modifying, deleting, or executing operations.

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 workspace_groups_info:
{
"version": "1",
"default": "deny",
"tools": {
"workspace_groups_info": {}
}
}workspace_groups_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve details about the workspace groups 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 workspace_groups_info: 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.
workspace_groups_info 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 workspace_groups_info 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 workspace_groups_info. 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.
workspace_groups_info 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.
