MOST DANGEROUS TOOLS

High Risk
Write · Low generate_cartesian_chart This tool generates and creates chart visualizations, which qualifies as Write (creates/modifies data reversibly). Write · Low generate_dual_axis_chart This tool generates interactive chart visualizations by creating new chart objects/definitions. Write · Low generate_dynamic_bar_chart This tool creates or modifies chart visualization data structures in a reversible manner. Write · Low generate_funnel_chart This tool creates (generates) a chart visualization, which is a reversible data creation action.

16 of Vchart's 16 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

HOW TO CONTROL VCHART

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

Rate limit write operations
{
  "generate_cartesian_chart": {
    "limits": [
      {
        "counter": "generate_cartesian_chart_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

  1. Create a free account and register Vchart — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

How do I prevent bulk modifications through Vchart? +

The Vchart server has 16 write tools including generate_cartesian_chart, generate_dual_axis_chart, generate_dynamic_bar_chart. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Vchart.

How many tools does the Vchart MCP server expose? +

16 tools across 1 categories: Write. 0 are read-only. 16 can modify, create, or delete data.

How do I enforce a policy on Vchart? +

Register the Vchart MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Vchart tool call.

Deterministic rules across all 16 Vchart tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
