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

AI agents call indicators_web_search to retrieve information from Technical Analysis 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 indicators_web_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 indicators_web_search tool do? +

Search the web for a technical indicator formula or Python implementation. FALLBACK TOOL: Only use this if you do not have native web browsing capabilities. If you have a native browser tool, please use that instead. Use this when list_indicators() confirms the indicator is NOT available in TA-Lib and you need to find the calculation formula or algorithm. CRITICAL: When looking for formulas, you MUST prioritize trusted financial authorities. Construct your query to include the keywords `investopedia.com` or `school.stockcharts.com` or `tradingview.com` unless the indicator is extremely obscure. Tips for effective queries: - Include 'Python' and 'pandas' for code-ready results - Include 'formula' or 'calculation' for mathematical definitions - Example: "SuperTrend indicator Python pandas formula site:investopedia.com OR site:school.stockcharts.com" Args: query: Search string (e.g. 'Keltner Channel python pandas calculation'). Returns: Top 5 web results with titles, URLs, and text snippets. . It is categorised as a Read tool in the Technical Analysis MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on indicators_web_search? +

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

What risk level is indicators_web_search? +

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

Can I rate-limit indicators_web_search? +

Yes. Add a rate_limit block to the indicators_web_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 indicators_web_search completely? +

Set action: deny in the Intercept policy for indicators_web_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 indicators_web_search? +

indicators_web_search is provided by the Technical Analysis MCP server (ta-mcp/technical-analysis-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
