MOST DANGEROUS TOOLS

High Risk

The most dangerous CVAT MCP tools

Execute · Critical cvat_api_request This tool is a general-purpose API proxy that can invoke any CVAT REST endpoint, including destructive DELETE operations, data-modifying POST/PATCH/PUT operations, and arbitrary executions. Write · Medium cvat_attach_task_data This tool creates or modifies data reversibly by attaching media files to annotation tasks. Write · Medium cvat_create_project This tool creates a new project resource in CVAT, which is a reversible write operation. Write · Medium cvat_create_task This tool creates a new annotation task resource in CVAT via a POST API call.

5 of CVAT MCP's 15 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control CVAT MCP

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

Rate limit write operations

{
  "cvat_attach_task_data": {
    "limits": [
      {
        "counter": "cvat_attach_task_data_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "cvat_get_api_schema": {
    "limits": [
      {
        "counter": "cvat_get_api_schema_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.

FAQ

Questions about CVAT MCP

How do I prevent bulk modifications through CVAT MCP? +

The CVAT MCP server has 4 write tools including cvat_attach_task_data, cvat_create_project, cvat_create_task. 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 CVAT MCP.

How many tools does the CVAT MCP server expose? +

15 tools across 3 categories: Destructive, Read, Write. 10 are read-only. 5 can modify, create, or delete data.

How do I enforce a policy on CVAT MCP? +

Register the CVAT 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 CVAT MCP tool call.

Deterministic rules across all 15 CVAT MCP tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
