## Why tv_health_check is rated Low

This tool performs health checking and retrieves the current state of a chart (Read category). It has no side effects, creates no resources, executes no code, and poses minimal security risk. The blast radius of misuse is negligible — an agent could only spam health checks or observe chart state, neither of which causes harm.

From the tool's own definition: "Tool description states 'Check CDP connection to TradingView and return current chart state' — a diagnostic/status check operation that retrieves information without modifying any data or executing user code."

## Use case

AI agents call tv_health_check 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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches TradingView MCP Bridge:

```json
