WHAT IT DOES

What snowflake_list_schemas does on Integrations MCP

AI agents call snowflake_list_schemas 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_schemas is rated Low

This tool retrieves schema metadata from Snowflake without modifying, deleting, or executing anything. It is a straightforward informational query. Severity is low because listing schemas has minimal blast radius unless the schema names themselves are considered sensitive, but such queries are standard practice for database inspection.

From the tool's definition Tool name is 'snowflake_list_schemas' and description states 'List all schemas in a Snowflake database' — a pure read operation that retrieves metadata with no side effects.

RECOMMENDED RULE

The rule that runs snowflake_list_schemas 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_schemas, this is the rule to start with:

snowflake_list_schemas Allowed

snowflake_list_schemas 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_schemas": {}
  }
}

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_schemas call is checked against it from then on.
