List all available databases in Snowflake
AI agents call list_databases to retrieve information from Snowflake MCP Server (Read-Only) without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves metadata about available databases without querying data, modifying anything, or executing code. It is a passive information discovery operation with minimal blast radius. Even if an AI agent misuses it, the worst outcome is learning what databases exist, which is low-impact reconnaissance.
From the tool's definition Tool name is 'list_databases' and description states it 'List all available databases in Snowflake'. Server is explicitly described as 'Read-Only' and this tool performs schema enumeration with no modification or execution capability.
Attacks that exploit this kind of access
List all available databases in Snowflake. It is categorised as a Read tool in the Snowflake MCP Server (Read-Only) MCP Server, which means it retrieves data without modifying state.
Register the Snowflake MCP Server (Read-Only) MCP server in PolicyLayer and add a rule for 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 Snowflake MCP Server (Read-Only). Nothing to install.
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 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 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.
list_databases is provided by the Snowflake MCP Server (Read-Only) MCP server (sgriffin-magnoliacap/mcp-snowflake-server-readonly). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
