WHAT IT DOES

What trend_analysis does on Metabase MCP

AI agents call trend_analysis to retrieve information from Metabase MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why trend_analysis is rated Low

This tool retrieves and analyzes existing time-series data to compute trend metrics, with no side effects on the underlying data. It performs computations on data already accessible via the Metabase server and does not create, modify, delete, or execute external operations.

From the tool's definition Tool name 'trend_analysis' with description 'Identify trends in time-series data' indicates data querying and analysis.

RECOMMENDED RULE

The rule that runs trend_analysis safely

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

trend_analysis Allowed

trend_analysis is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "trend_analysis": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Metabase MCP, apply this rule, and every trend_analysis call is checked against it from then on.
