resume_workspace

THE RISK

High Risk

Resuming a suspended workspace triggers an external operational state change — it starts compute resources and makes the workspace active again. This is an Execute-category action (triggering external operations) with high severity because it can incur costs, change system availability, and affect downstream workloads at scale.

HOW TO CONTROL RESUME_WORKSPACE

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 resume_workspace:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "resume_workspace": {
      "limits": [
        {
          "counter": "resume_workspace_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

resume_workspace stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register SingleStore MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the resume_workspace tool do? +

Resume a suspended workspace. It is categorised as a Execute tool in the SingleStore MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on resume_workspace? +

Register the SingleStore MCP Server MCP server in PolicyLayer and add a rule for resume_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 SingleStore MCP Server. Nothing to install.

What risk level is resume_workspace? +

resume_workspace is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit resume_workspace? +

Yes. Add a rate_limit block to the resume_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.

How do I block resume_workspace completely? +

Set action: deny in the PolicyLayer policy for resume_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.

What MCP server provides resume_workspace? +

resume_workspace 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.

Enforce policy on every SingleStore MCP Server tool call.
