WHAT IT DOES

What watchlist_add does on TradingView MCP Server

AI agents use watchlist_add to create or update resources in TradingView MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TradingView MCP Server environment.

RISK

Why watchlist_add is rated Medium

The tool creates or modifies watchlist state by appending a symbol, which is reversible and has no side effects beyond the watchlist itself. It does not delete data (not Destructive), execute arbitrary code (not Execute), trigger financial transactions (not Financial), or retrieve data (not Read). The blast radius is low since adding a symbol to a watchlist is benign and easily undone.

From the tool's definition Tool name 'watchlist_add' and description 'Add a symbol to the TradingView watchlist' indicate a create/modify operation that adds data to a watchlist. This is a reversible write operation—symbols can be removed later.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs watchlist_add safely

PolicyLayer is an MCP gateway: it sits between your AI agents and TradingView MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For watchlist_add, this is the rule to start with:

watchlist_add Rate-limited

watchlist_add 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.
