MOST DANGEROUS TOOLS

High Risk

The most dangerous MCP Data Visualization Server tools

Execute · High query_data This tool runs arbitrary SQL queries against a database. Write · Low configure_chart The tool modifies chart parameters and settings based on user responses to selection questions. Write · Medium create_interactive_dashboard This tool creates new data artifacts (HTML dashboards) that persist and can be shared or modified later. Write · Low create_sample_chart This tool creates sample data visualizations for development/testing purposes.

10 of MCP Data Visualization Server's 28 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control MCP Data Visualization Server

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Data Visualization Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "change_database": {
    "limits": [
      {
        "counter": "change_database_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "start_visualization_wizard": {
    "limits": [
      {
        "counter": "start_visualization_wizard_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
