Search Korean stock market themes by keyword (Korean or English). Use when the user asks about a specific sector, industry, investment theme, stock name, or stock code. Searches theme names, related stock names, and stock symbols. Examples: "AI", "반도체" (semiconductor), "2차전지" (EV battery), "방산"...

Part of the Stockmatrix MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call search_themes to retrieve information from Stockmatrix 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 search_themes 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.

Search Korean stock market themes by keyword (Korean or English). Use when the user asks about a specific sector, industry, investment theme, stock name, or stock code. Searches theme names, related stock names, and stock symbols. Examples: "AI", "반도체" (semiconductor), "2차전지" (EV battery), "방산" (defense), "로봇" (robotics), "원자력" (nuclear), "삼성전자" (Samsung), "005930". Returns matching themes with TLI scores and lifecycle stages. Use the returned theme_id with get_theme_detail or get_theme_history for deeper analysis.. It is categorised as a Read tool in the Stockmatrix MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for search_themes. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Stockmatrix MCP server.
search_themes 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 search_themes 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 search_themes. 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.
search_themes is provided by the Stockmatrix MCP server (stockmatrix-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
