Query OBProxy cluster list This interface is used to query OBProxy cluster list information. The caller must be authenticated through OCP application service. Args: page: Pagination page number, starting from 1, default: 1 size: Pagination size, default: 10 Returns: Dictionary containing OBProxy ...
AI agents call list_obproxy_clusters to retrieve information from Mcp Oceanbase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists OBProxy cluster information. It accepts only pagination parameters (page, size) for querying existing data and returns cluster metadata. There are no arguments that suggest modification, deletion, code execution, or financial operations. Authentication is required but does not change the fundamental read-only nature of the operation.
From the tool's definition Tool name is 'list_obproxy_clusters' and description states 'Query OBProxy cluster list' — both indicate data retrieval without modification.
Documented attack patterns abuse exactly the kind of access list_obproxy_clusters 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 list_obproxy_clusters:
{
"version": "1",
"default": "deny",
"tools": {
"list_obproxy_clusters": {}
}
}list_obproxy_clusters is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Query OBProxy cluster list This interface is used to query OBProxy cluster list information. The caller must be authenticated through OCP application service. Args: page: Pagination page number, starting from 1, default: 1 size: Pagination size, default: 10 Returns: Dictionary containing OBProxy cluster list and pagination information. It is categorised as a Read tool in the Mcp Oceanbase MCP Server, which means it retrieves data without modifying state.
Register the Mcp Oceanbase MCP server in PolicyLayer and add a rule for list_obproxy_clusters: 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.
list_obproxy_clusters is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_obproxy_clusters 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 list_obproxy_clusters. 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.
list_obproxy_clusters 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.
