rabqatab/lexlink-ko-mcp Read Risk 2/5

AI agents call expc_search to retrieve information from Korean Law Search 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 expc_search 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.

What does the expc_search tool do? +

Args: query: Search keyword (default "*") display: Number of results per page (max 100, default 20). **Recommend 50-100 for searches to ensure exact matches are found.** page: Page number (1-based, default 1) oc: Optional OC override (defaults to env var) type: Response format - "JSON" (default), "XML", or "HTML" search: 1=법령해석례명 (interpretation name, default), 2=본문검색 (full text) inq: Inquiry organization name rpl: Reply organization code gana: Dictionary-style search (ga, na, da, ...) itmno: Item number (e.g., 13-0217 → 130217) reg_yd: Registration date range (YYYYMMDD~YYYYMMDD) expl_yd: Interpretation date range (YYYYMMDD~YYYYMMDD) sort: Sort order - "lasc"|"ldes"|"dasc"|"ddes"|"nasc"|"ndes" pop_yn: Popup mode - "Y" or "N" ctx: MCP context (injected automatically) Returns: Search results with legal interpretations list or error Examples: Search for "임차": >>> expc_search(query="임차", display=10, type="XML") Search by date range: >>> expc_search(query="자동차", expl_yd="20240101~20241231", type="XML") . It is categorised as a Read tool in the Korean Law Search MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on expc_search? +

Add a rule in your Intercept YAML policy under the tools section for expc_search. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Korean Law Search MCP server.

What risk level is expc_search? +

expc_search is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit expc_search? +

Yes. Add a rate_limit block to the expc_search 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.

How do I block expc_search completely? +

Set action: deny in the Intercept policy for expc_search. 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.

What MCP server provides expc_search? +

expc_search is provided by the Korean Law Search MCP server (rabqatab/lexlink-ko-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
