Show or hide an indicator/study on the chart
AI agents use indicator_toggle_visibility to create or update resources in TradingView MCP Bridge — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TradingView MCP Bridge environment.
This tool modifies the visibility state of an indicator on a TradingView chart — a reversible UI state change (toggle on/off). It does not delete data, execute code, or involve financial transactions. It's a write operation with low blast radius since it only affects chart display and can be easily undone.

Documented attack patterns abuse exactly the kind of access indicator_toggle_visibility gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and TradingView MCP Bridge, and nothing reaches the server without passing your rules. This is the rule we recommend for indicator_toggle_visibility:
{
"version": "1",
"default": "deny",
"tools": {
"indicator_toggle_visibility": {
"limits": [
{
"counter": "indicator_toggle_visibility_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}indicator_toggle_visibility stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
