Part of the Stockmatrix MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call search_stocks 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_stocks 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 stocks by company name, symbol, or 6-digit stock code, and preview their related themes. Use when the user asks: - Find Samsung Electronics / 삼성전자 - I only know the company name, not the stock code - 종목명으로 코드 찾고 관련 테마도 보고 싶어 - 삼성전자가 속한 테마 알려줘 / what themes is Samsung in? - 005930 테마 알려줘 / which themes is this stock part of? For 6-digit stock codes, automatically performs a detailed stock-to-theme lookup (replaces get_stock_theme). For text queries, searches by company name and returns matching stocks with theme previews.. 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_stocks. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Stockmatrix MCP server.
search_stocks 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_stocks 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_stocks. 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_stocks 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.
Open source. One binary. Zero dependencies.
