Delete a document from an index.
AI agents call delete_document to permanently remove resources in OpenSearch MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes documents from an OpenSearch index without the ability to undo the operation. Deletion is irreversible and constitutes data loss. While individual document deletion has a narrower blast radius than cluster-level destructive operations, it still represents irreversible data modification and warrants high severity. If an AI agent misuses this tool, documents could be unrecoverably lost.
From the tool's definition Tool name 'delete_document' combined with description 'Delete a document from an index' indicates irreversible removal of data from OpenSearch.

Delete a document from an index. It is categorised as a Destructive tool in the OpenSearch MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the OpenSearch MCP Server MCP server in PolicyLayer and add a rule for delete_document: 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 OpenSearch MCP Server. Nothing to install.
delete_document 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_document 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_document. 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_document is provided by the OpenSearch MCP Server MCP server (suriyakumar-hait/opensearch_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
delete_document is one line of OpenSearch MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
