Manage fuses on a wrapped ENS name. Fuses are permission bits that can be permanently burned to restrict what can be done with a name. Three modes: 1. read — Check which fuses are currently burned on a name 2. burn_owner_fuses — Burn fuses on a name you own (CANNOT_UNWRAP must be burned first) 3....

AI agents may call manage_fuses to permanently remove or destroy resources in Name Whisper — ENS Intelligence Layer. 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 manage_fuses in a loop, permanently destroying resources in Name Whisper — ENS Intelligence Layer. 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.

Manage fuses on a wrapped ENS name. Fuses are permission bits that can be permanently burned to restrict what can be done with a name. Three modes: 1. read — Check which fuses are currently burned on a name 2. burn_owner_fuses — Burn fuses on a name you own (CANNOT_UNWRAP must be burned first) 3. burn_child_fuses — As a parent, burn fuses on a subname (e.g. burn PARENT_CANNOT_CONTROL on sub.parent.eth) Owner-controlled fuses: - CANNOT_UNWRAP — prevents unwrapping (MUST be burned first before any other fuse) - CANNOT_BURN_FUSES — prevents burning additional fuses - CANNOT_TRANSFER — prevents transfers - CANNOT_SET_RESOLVER — prevents resolver changes - CANNOT_SET_TTL — prevents TTL changes - CANNOT_CREATE_SUBDOMAIN — prevents creating new subnames - CANNOT_APPROVE — prevents approving operators Parent-controlled fuses (for subnames): - PARENT_CANNOT_CONTROL — parent permanently gives up control over the subname - CAN_EXTEND_EXPIRY — allows the subname owner to extend their own expiry WARNING: All fuse burning is IRREVERSIBLE. Fuses expire when the name expires.. It is categorised as a Destructive tool in the Name Whisper — ENS Intelligence Layer MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Name Whisper — ENS Intelligence Layer MCP server in PolicyLayer and add a rule for manage_fuses: 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 Name Whisper — ENS Intelligence Layer. Nothing to install.
manage_fuses 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 manage_fuses 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 manage_fuses. 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.
manage_fuses is provided by the Name Whisper — ENS Intelligence Layer MCP server (https://namewhisper.ai/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
