MOST DANGEROUS TOOLS

High Risk

The most dangerous JVLink MCP Server tools

Execute · High execute_template_query This tool generates SQL from templates and executes them against a database. Execute · High update_server This tool executes shell-level operations (git pull and dependency installation) on the server environment. Execute · High keiba_data_search The tool allows free-form SQL queries against the horse racing database.

3 of JVLink MCP Server's 25 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control JVLink MCP Server

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

Cap read operations

{
  "favorite_performance": {
    "limits": [
      {
        "counter": "favorite_performance_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Create a free account and register JVLink MCP Server — nothing to install.
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.
