AI agents call get_rsi to retrieve information from TradingView MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
RSI is a standard technical analysis indicator used to measure momentum. The 'get_' prefix combined with the indicator name clearly indicates data retrieval with no side effects. This is purely informational analysis of market data, similar to all other indicator retrieval tools on the server. The server overall is analysis-focused rather than order-placement or fund-movement focused.
From the tool's definition Tool name is 'get_rsi' which retrieves the Relative Strength Index (RSI) technical indicator value. The pattern matches sibling tools like 'get_adx', 'get_atr', and 'get_bollinger_bands' which are all data retrieval functions for technical indicators.

PolicyLayer is an MCP gateway — it sits between your AI agents and TradingView MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_rsi:
{
"version": "1",
"default": "deny",
"tools": {
"get_rsi": {}
}
}get_rsi is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_rsi. It is categorised as a Read tool in the TradingView MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TradingView MCP Server MCP server in PolicyLayer and add a rule for get_rsi: 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 Server. Nothing to install.
get_rsi is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_rsi 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 get_rsi. 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.
get_rsi is provided by the TradingView MCP Server MCP server (lev-corrupted/tradingviewmcpserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from TradingView MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
