AI agents may call survey_site 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 survey_site 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.

These attack patterns abuse exactly the kind of access survey_site gives an agent. Each links to the full case and the policy that stops it:
Other destructive tools across the catalogue. The same approach applies to each: deny by default, or require human approval.
Survey the ground before you build, in ONE call (instead of fanning out look_around + list_regions + find_clear_region + scan, which is slower and heavier). Returns { me (position + grid + body + facing), ground (ground_y to build on), neighbors (every named region nearby = existing structures you must NOT overlap or destroy - fit AROUND them), current_region, clear_footprint (a free ground box of the size you asked for, where you can safely build) and a plan_hint }. Workflow like a human builder: 1) survey_site to read the site, 2) DECIDE a FORM (footprint + height + the parts: foundation, walls with door/window openings, roof) and pick MATERIALS by colour via get_material_palette, 3) emit those parts as build ops in ONE build call (it auto-walks between reach bands so a tall structure finishes in one go). Pass size:[w,h,d] (cells) to also reserve a clear footprint.. 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.
Register the Space0 MCP server in PolicyLayer and add a rule for survey_site: 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.
survey_site is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the survey_site 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 survey_site. 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.
survey_site 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.
