MOST DANGEROUS TOOLS

High Risk

The most dangerous Multi-Database SQL MCP Server tools

Execute · High execute_query While this tool could be used for read operations, the ability to execute parameterized SQL queries means it can also perform writes, modifications, and potentially destructive operations (UPDATE, DELETE, DROP) depending Write · Medium connect_database Connecting to a database creates a new persistent connection resource (state side effect) but does not read, modify, or destroy data. Write · Medium disconnect_database This tool modifies system state by terminating a database connection, which is a reversible Write action rather than a Read (no side effects) or Destructive (irreversible data deletion).

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

POLICY

How to control Multi-Database SQL MCP Server

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

Rate limit write operations

{
  "connect_database": {
    "limits": [
      {
        "counter": "connect_database_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_table_schema": {
    "limits": [
      {
        "counter": "get_table_schema_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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