List all warehouses accessible to the current user in Snowflake.
AI agents call snowflake_list_warehouses to retrieve information from Integrations MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries warehouse metadata from Snowflake without side effects. It performs a straightforward data retrieval operation that does not create, modify, delete, or execute any operations. The read-only nature and low blast radius (information disclosure only) justify the low severity.
From the tool's definition Tool name contains 'list' and description explicitly states 'List all warehouses' with no indication of modification or deletion capabilities.
Attacks that exploit this kind of access
List all warehouses accessible to the current user in Snowflake. It is categorised as a Read tool in the Integrations MCP MCP Server, which means it retrieves data without modifying state.
Register the Integrations MCP server in PolicyLayer and add a rule for snowflake_list_warehouses: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Integrations MCP. Nothing to install.
snowflake_list_warehouses is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the snowflake_list_warehouses rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for snowflake_list_warehouses. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
snowflake_list_warehouses is provided by the Integrations MCP server (shriram-vasudevan/integrations-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
