List all databases accessible to the current user in Snowflake.
AI agents call snowflake_list_databases 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 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
List all databases 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_databases: 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_databases 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_databases 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_databases. 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_databases 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.
