AI agents use create_cluster to create or update resources in Mcp Oceanbase — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Oceanbase environment.
The tool name clearly suggests resource creation ('create_cluster') in the context of OceanBase, a distributed database system. While the description is empty, cluster creation is a consequential operation that modifies infrastructure state and is typically reversible (unlike deletion), placing it in the Write category.
From the tool's definition Tool name 'create_cluster' indicates creation of a new cluster resource, typically an irreversible provisioning operation in database systems like OceanBase.
Documented attack patterns abuse exactly the kind of access create_cluster 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 create_cluster:
{
"version": "1",
"default": "deny",
"tools": {
"create_cluster": {
"limits": [
{
"counter": "create_cluster_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_cluster stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

create_cluster. It is categorised as a Write tool in the Mcp Oceanbase MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Oceanbase MCP server in PolicyLayer and add a rule for create_cluster: 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.
create_cluster is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_cluster 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 create_cluster. 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.
create_cluster 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.
