Create a price alert via the TradingView alert dialog
AI agents use alert_create 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 creates new alert objects in TradingView, which is a Write operation—data creation without destruction. While alerts can trigger notifications and potentially automated trades depending on TradingView's connected systems, the tool itself only creates the alert configuration, not execute trades.
From the tool's definition Tool name 'alert_create' and description 'Create a price alert' indicate data creation. TradingView alerts are user-created configuration objects that persist but are reversibly modifiable (via alert_delete and related management tools on the server).
Documented attack patterns abuse exactly the kind of access alert_create 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 alert_create:
{
"version": "1",
"default": "deny",
"tools": {
"alert_create": {
"limits": [
{
"counter": "alert_create_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}alert_create 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.

Create a price alert via the TradingView alert dialog. It is categorised as a Write tool in the TradingView MCP Bridge MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the TradingView MCP Bridge MCP server in PolicyLayer and add a rule for alert_create: 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 MCP Bridge. Nothing to install.
alert_create is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the alert_create 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 alert_create. 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.
alert_create is provided by the TradingView MCP Bridge MCP server (tradesdontlie/tradingview-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
