AI agents call get_theme_history 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 get_theme_history 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.

Get 30-day score history for a Korean stock theme. Returns daily TLI scores and stage transitions for trend analysis. Use when the user asks about theme momentum over time, whether a theme is gaining or losing interest, or wants to see historical trajectory. Answers: "이 테마 추세가 어때?", "최근 한달 흐름", "is this theme gaining or losing momentum?", "show me the trend".. It is categorised as a Read tool in the Stockmatrix MCP Server, which means it retrieves data without modifying state.
Register the Stockmatrix MCP server in PolicyLayer and add a rule for get_theme_history: 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 Stockmatrix. Nothing to install.
get_theme_history 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 get_theme_history 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 get_theme_history. 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.
get_theme_history is provided by the Stockmatrix MCP server (stockmatrix-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
