MOST DANGEROUS TOOLS

High Risk

The most dangerous Snowflake MCP Server tools

Execute · High execute_query Despite the server marketing itself as 'read-only access', the tool name 'execute_query' directly implies execution of arbitrary SQL queries. Execute · High execute_query_to_file This tool both executes queries (which could include destructive SQL despite the server's 'read-only' claim) and writes to arbitrary file paths on the filesystem. Execute · Low refresh_catalog This tool triggers an external operation (refreshing/rebuilding the internal schema catalog cache), which goes beyond a simple read.

3 of Snowflake MCP Server's 7 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Snowflake MCP Server

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

Cap read operations

{
  "describe_table": {
    "limits": [
      {
        "counter": "describe_table_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 Snowflake 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.
