MOST DANGEROUS TOOLS

High Risk

The most dangerous MelviChat MCP Server tools

Execute · High execute_sql_query This tool runs SQL commands against a production database (RetailPOS_DB). Execute · High chat_with_database The tool name 'chat_with_database' implies executing queries or commands against a database through a natural language interface. Execute · High query_ai_agent This tool invokes an external AI agent (Google Gemini) to query/reason about the main database. Execute · High query_registered_database This tool executes arbitrary SQL queries directly against a registered database.

6 of MelviChat MCP Server's 13 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control MelviChat MCP Server

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

Rate limit write operations

{
  "login": {
    "limits": [
      {
        "counter": "login_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_database_schema": {
    "limits": [
      {
        "counter": "get_database_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.
