WHAT IT DOES

What replay_start does on TradingView MCP Bridge

AI agents invoke replay_start to trigger actions in TradingView MCP Bridge. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why replay_start is rated High

This tool executes a command that changes the state and behavior of the TradingView application (entering replay mode). While not destructive or financial, it actively triggers external operations whose effects depend on provided arguments (the optional date parameter).

From the tool's definition Tool 'replay_start' initiates bar replay mode in TradingView, which is an active operation that triggers a specific workflow state in the application.

RECOMMENDED RULE

The rule that runs replay_start safely

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

replay_start Rate-limited

replay_start stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
