WHAT IT DOES

What snowflake_list_databases does on Integrations MCP

AI agents call snowflake_list_databases to retrieve information from Integrations MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why snowflake_list_databases is rated Low

This tool retrieves metadata about available databases without side effects. It performs a read-only query against Snowflake, returning information the current user already has access to view. No data is created, modified, deleted, or executed. The blast radius is minimal as it only exposes information about database availability.

From the tool's definition Tool name explicitly states 'list' and description specifies 'List all databases accessible to the current user in Snowflake' - a query operation with no data modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs snowflake_list_databases safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Integrations MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For snowflake_list_databases, this is the rule to start with:

snowflake_list_databases Allowed

snowflake_list_databases is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "snowflake_list_databases": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Integrations MCP, apply this rule, and every snowflake_list_databases call is checked against it from then on.
