WHAT IT DOES

What tv_discover does on TradingView MCP Bridge

AI agents call tv_discover to retrieve information from TradingView MCP Bridge without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why tv_discover is rated Low

This is a discovery/introspection tool that queries metadata about available API paths and their HTTP methods. It performs no side effects, modifies no state, executes no code, and involves no financial operations. The worst-case misuse would be reconnaissance for a subsequent attack, but the tool itself is read-only.

From the tool's definition Tool description states it 'Report[s] which known TradingView API paths are available and their methods' — purely informational discovery of available endpoints with no data retrieval, modification, execution, or financial impact.
