Part of the Cls MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call SearchLog to retrieve information from Cls without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though SearchLog only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

SQL 分析（管道符 |）： - 聚合统计：* | SELECT count(*) AS total - 分组统计：* | SELECT count(*) AS cnt, level GROUP BY level - 排序限制：* | SELECT count(*) AS cnt, host GROUP BY host ORDER BY cnt DESC LIMIT 10 - 条件过滤：* | SELECT * WHERE response_time > 1000. It is categorised as a Read tool in the Cls MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for SearchLog. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Cls MCP server.
SearchLog 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 SearchLog rule in your Intercept 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 Intercept policy for SearchLog. 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.
SearchLog is provided by the Cls MCP server (cls-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
