Update OceanBase cluster parameters This interface is used to update parameters of the target OceanBase cluster. Args: cluster_id: The ID of the target cluster parameters: Parameter list containing parameter names and new values Returns: OCP API response data
AI agents use set_oceanbase_cluster_parameters 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.
This tool modifies cluster configuration settings but does not delete data or execute arbitrary code. The effect is reversible (parameters can be changed back to previous values), making it a Write operation. Severity is high because misconfigured cluster parameters could impact database availability, performance, or security, affecting all tenants on that cluster.
From the tool's definition Tool description explicitly states 'Update OceanBase cluster parameters' with arguments for cluster_id and new parameter values, indicating modification of cluster configuration.
Documented attack patterns abuse exactly the kind of access set_oceanbase_cluster_parameters 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 set_oceanbase_cluster_parameters:
{
"version": "1",
"default": "deny",
"tools": {
"set_oceanbase_cluster_parameters": {
"limits": [
{
"counter": "set_oceanbase_cluster_parameters_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_oceanbase_cluster_parameters 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.

Update OceanBase cluster parameters This interface is used to update parameters of the target OceanBase cluster. Args: cluster_id: The ID of the target cluster parameters: Parameter list containing parameter names and new values Returns: OCP API response data. 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 set_oceanbase_cluster_parameters: 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.
set_oceanbase_cluster_parameters 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 set_oceanbase_cluster_parameters 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 set_oceanbase_cluster_parameters. 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.
set_oceanbase_cluster_parameters 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.
