Delete an Elasticsearch index
AI agents call delete_index to permanently remove resources in Octodet Elasticsearch — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting an index in Elasticsearch is a destructive action that irreversibly removes all documents and metadata associated with that index. This cannot be undone without a backup restore. While the blast radius depends on which index is targeted, the destructive nature of the operation itself warrants the Destructive category over Execute, and high severity due to potential data loss impact.
From the tool's definition Tool name is 'delete_index' with description 'Delete an Elasticsearch index'. The verb 'delete' combined with the scope 'index' (an entire data structure) indicates irreversible removal of data.
Attacks that exploit this kind of access
Delete an Elasticsearch index. It is categorised as a Destructive tool in the Octodet Elasticsearch MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Octodet Elasticsearch MCP server in PolicyLayer and add a rule for delete_index: 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 Octodet Elasticsearch. Nothing to install.
delete_index 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_index 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_index. 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_index is provided by the Octodet Elasticsearch MCP server (octodet/elasticsearch-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
