List all workspaces you have access to.
AI agents call list_workspaces to retrieve information from RunWhen Platform MCP 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 workspace data without modifying, executing operations, or causing irreversible changes. It is purely informational, making it a Read category tool with low severity risk.
From the tool's definition Tool name and description indicate 'List all workspaces you have access to' — a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all workspaces you have access to. It is categorised as a Read tool in the RunWhen Platform MCP MCP Server, which means it retrieves data without modifying state.
Register the RunWhen Platform MCP server in PolicyLayer and add a rule for list_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 RunWhen Platform MCP. Nothing to install.
list_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_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_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_workspaces is provided by the RunWhen Platform MCP server (runwhen-contrib/runwhen-platform-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
