AI agents may call leave_space to permanently remove or destroy resources in Space0. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.

Without a policy, an AI agent could call leave_space in a loop, permanently destroying resources in Space0. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so leave_space only ever does what you allow.

What does the leave_space tool do? +

Remove your body from a space you entered.. It is categorised as a Destructive tool in the Space0 MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on leave_space? +

Register the Space0 MCP server in PolicyLayer and add a rule for leave_space: 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 Space0. Nothing to install.

What risk level is leave_space? +

leave_space is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit leave_space? +

Yes. Add a rate_limit block to the leave_space 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 leave_space completely? +

Set action: deny in the PolicyLayer policy for leave_space. 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 leave_space? +

leave_space is provided by the Space0 MCP server (https://mcp.0.space/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Space0 tool call.
