MCP Tool Reference Medium Risk

select_workspace

Select a workspace to use

Part of the Render MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

render-oss/render-mcp-server Write

WHEN AI AGENTS USE THIS TOOL

AI agents use select_workspace to create or modify resources in Render. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

WHY ENFORCE A POLICY ON SELECT_WORKSPACE

Without a policy, an AI agent could call select_workspace repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Render.

RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

render.yaml 
tools:
  select_workspace:
    rules:
      - action: allow
        rate_limit:
          max: 30
          window: 60

FREQUENTLY ASKED QUESTIONS

What does the select_workspace tool do?

Select a workspace to use. It is categorised as a Write tool in the Render MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on select_workspace?

Add a rule in your Intercept YAML policy under the tools section for select_workspace. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Render MCP server.

What risk level is select_workspace?

select_workspace is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit select_workspace?

Yes. Add a rate_limit block to the select_workspace rule in your Intercept 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 select_workspace completely?

Set action: deny in the Intercept policy for select_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 select_workspace?

select_workspace is provided by the Render MCP server (render-oss/render-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
