AI agents may call emem_wave_solve to permanently remove or destroy resources in emem — Earth memory protocol. 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 emem_wave_solve in a loop, permanently destroying resources in emem — Earth memory protocol. 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 emem_wave_solve 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.
Forward-step 1-D explicit finite-difference solver for the shallow-water wave equation ∂²u/∂t² = c²∂²u/∂x² with c² = g·h, where depth h comes from gmrt.topobathy_mean along the seaward gradient. Models how an offshore swell of height H_s and period T propagates toward coastal_cell. Returns arrival height + time + depth + phase-speed profiles, all under a CFL-stable timestep. When to use: Use when the user wants to predict swell arrival at a coast (storm-surge planning, shoreline-impact assessment, surf forecasting). The solver walks n_offshore_cells cells seaward from coastal_cell along the bathymetric gradient (default 8 cells = 80 m of profile at the active 10 m grid), samples GMRT depth at each, and integrates the wave equation forward until the wavefront reaches the coast plus one period. Receipt cites every depth fact CID along the profile. Returns 422 with a clear message if coastal_cell is land-locked.. It is categorised as a Destructive tool in the emem — Earth memory protocol MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the emem — Earth memory protocol MCP server in PolicyLayer and add a rule for emem_wave_solve: 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 emem — Earth memory protocol. Nothing to install.
emem_wave_solve 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 emem_wave_solve 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 emem_wave_solve. 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.
emem_wave_solve is provided by the emem — Earth memory protocol MCP server (oci:ghcr.io/vortx-ai/emem:latest). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
