Close a lease on-chain. This is permanent — the lease cannot be reopened after closing.
AI agents call close_lease to permanently remove resources in Manifest MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool explicitly states the action is permanent and irreversible. Closing a blockchain lease on-chain cannot be undone, matching the Destructive category. The critical severity reflects the financial and operational impact of permanently terminating a cloud/compute lease on a decentralized network.
From the tool's definition 'Close a lease on-chain. This is permanent — the lease cannot be reopened after closing.'
Attacks that exploit this kind of access
Close a lease on-chain. This is permanent — the lease cannot be reopened after closing. It is categorised as a Destructive tool in the Manifest MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Manifest MCP server in PolicyLayer and add a rule for close_lease: 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 Manifest MCP. Nothing to install.
close_lease 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 close_lease 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 close_lease. 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.
close_lease is provided by the Manifest MCP server (manifest-network/manifest-mcp-mono). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
