Get MACD crossover signals and divergence analysis. Args: ticker: Stock ticker symbol fast_period: Fast EMA period (default 12) slow_period: Slow EMA period (default 26) signal_period: Signal line period (default 9) days: Number of days of historical data (default 365)
AI agents call get_macd_analysis to retrieve information from MaverickMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes historical stock price data to compute MACD (Moving Average Convergence Divergence) technical indicators. It performs calculations on existing data and returns analytical results without modifying any state, executing arbitrary code, or committing financial transactions. The most severe action is read-only data retrieval with local computation of standard technical analysis metrics.
From the tool's definition Tool name 'get_macd_analysis' and description 'Get MACD crossover signals and divergence analysis' indicates data retrieval. Arguments are all read-only parameters (ticker symbol, period settings, historical data range).
Documented attack patterns abuse exactly the kind of access get_macd_analysis gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MaverickMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_macd_analysis:
{
"version": "1",
"default": "deny",
"tools": {
"get_macd_analysis": {}
}
}get_macd_analysis is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get MACD crossover signals and divergence analysis. Args: ticker: Stock ticker symbol fast_period: Fast EMA period (default 12) slow_period: Slow EMA period (default 26) signal_period: Signal line period (default 9) days: Number of days of historical data (default 365). It is categorised as a Read tool in the MaverickMCP MCP Server, which means it retrieves data without modifying state.
Register the Maverick MCP server in PolicyLayer and add a rule for get_macd_analysis: 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 MaverickMCP. Nothing to install.
get_macd_analysis 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_macd_analysis 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_macd_analysis. 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_macd_analysis is provided by the Maverick MCP server (wshobson/maverick-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
