AI agents call delete_documents to permanently remove resources in Mcp Oceanbase — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool performs document deletion, which is an irreversible operation that removes data permanently. Even without a detailed description, the name clearly conveys destruction semantics. Given the OceanBase database context (a SQL database system), this likely operates on stored documents/records.
From the tool's definition Tool name is 'delete_documents' which directly indicates irreversible deletion of data. Description is empty, but the function name unambiguously describes a destructive operation.
Documented attack patterns abuse exactly the kind of access delete_documents gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Oceanbase, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_documents:
{
"version": "1",
"default": "deny",
"hide": [
"delete_documents"
]
}delete_documents disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

delete_documents. It is categorised as a Destructive tool in the Mcp Oceanbase MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Oceanbase MCP server in PolicyLayer and add a rule for delete_documents: 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 Mcp Oceanbase. Nothing to install.
delete_documents 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_documents 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_documents. 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_documents is provided by the Mcp Oceanbase MCP server (oceanbase/awesome-oceanbase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
