分析集群日志，找出发生过的错误信息并返回 :param cluster_name: 集群配置文件名前缀，可选。如 ob_test 表示使用 ~/.obdiag/ob_test.yml。不传则使用默认 config.yml :return: 指令执行的输出结果
AI agents call obdiag_analyze_log 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 performs log analysis and retrieval only. It examines historical log data to identify errors and returns results. No data is modified, deleted, or created; no code is executed on the system; and no financial operations occur. The operation is read-only with no side effects beyond retrieving information from existing logs.
From the tool's definition Tool name 'obdiag_analyze_log' and description states '分析集群日志，找出发生过的错误信息并返回' (analyze cluster logs, find occurred error messages and return).
Documented attack patterns abuse exactly the kind of access obdiag_analyze_log 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 obdiag_analyze_log:
{
"version": "1",
"default": "deny",
"tools": {
"obdiag_analyze_log": {}
}
}obdiag_analyze_log is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

分析集群日志，找出发生过的错误信息并返回 :param cluster_name: 集群配置文件名前缀，可选。如 ob_test 表示使用 ~/.obdiag/ob_test.yml。不传则使用默认 config.yml :return: 指令执行的输出结果. 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 obdiag_analyze_log: 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.
obdiag_analyze_log 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 obdiag_analyze_log 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 obdiag_analyze_log. 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.
obdiag_analyze_log 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.
