Part of the Stockmatrix MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents call compare_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 compare_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.

What does the compare_themes tool do? +

Compare 2–5 Korean stock market themes side-by-side with lifecycle scores, similarity, and overlapping stocks. Use when the user asks: - Compare semiconductor and AI themes - How similar are these themes? - 반도체 vs AI 테마 비교, 테마 간 유사도 - Which theme is stronger right now? - Do these themes share the same stocks? Returns each theme's score/stage/sparkline, pairwise similarity scores, and overlapping stocks.. It is categorised as a Read tool in the Stockmatrix MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on compare_themes? +

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

What risk level is compare_themes? +

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

Can I rate-limit compare_themes? +

Yes. Add a rate_limit block to the compare_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.

How do I block compare_themes completely? +

Set action: deny in the Intercept policy for compare_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.

What MCP server provides compare_themes? +

compare_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.
