delete_ssh_key
AI agents call delete_ssh_key to permanently remove resources in Nebulablock — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
SSH keys are security credentials used for authentication and access control. Deleting an SSH key is irreversible and cannot be undone without manual re-provisioning. This qualifies as Destructive rather than Write since the operation cannot be reversed through normal API operations.
From the tool's definition Tool name is 'delete_ssh_key' which performs a delete operation on SSH key credentials.
Attacks that exploit this kind of access
delete_ssh_key. It is categorised as a Destructive tool in the Nebulablock MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Nebulablock MCP server in PolicyLayer and add a rule for delete_ssh_key: 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 Nebulablock. Nothing to install.
delete_ssh_key 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 delete_ssh_key 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 delete_ssh_key. 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.
delete_ssh_key is provided by the Nebulablock MCP server (nebula-block-data/nebulablock-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
