Rank symbols by weighted technical analysis scores across timeframes. Useful for comparing which symbols have the strongest overall TA signals.
AI agents call rank_by_ta to retrieve information from Tradingview without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though rank_by_ta only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Rank symbols by weighted technical analysis scores across timeframes. Useful for comparing which symbols have the strongest overall TA signals. It is categorised as a Read tool in the Tradingview MCP Server, which means it retrieves data without modifying state.
Register the Tradingview MCP server in PolicyLayer and add a rule for rank_by_ta: 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 Tradingview. Nothing to install.
rank_by_ta 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 rank_by_ta 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 rank_by_ta. 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.
rank_by_ta is provided by the Tradingview MCP server (tradingview-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
