List all tables in a specific database and schema
AI agents call list_tables to retrieve information from Mcp Snowflake Server No Write System Prompt 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 tables without creating, modifying, or deleting any data. It is a read-only operation that lists existing database objects. The server explicitly disallows write operations, further confirming this is safe retrieval. The blast radius is minimal—an agent listing tables cannot cause harm beyond information disclosure, which is low-severity.
From the tool's definition Tool name 'list_tables' and description 'List all tables in a specific database and schema' indicate a querying/retrieval operation with no data modification capability.
Attacks that exploit this kind of access
List all tables in a specific database and schema. It is categorised as a Read tool in the Mcp Snowflake Server No Write System Prompt MCP Server, which means it retrieves data without modifying state.
Register the Mcp Snowflake Server No Write System Prompt MCP server in PolicyLayer and add a rule for list_tables: 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 Mcp Snowflake Server No Write System Prompt. Nothing to install.
list_tables 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_tables 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_tables. 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_tables is provided by the Mcp Snowflake Server No Write System Prompt MCP server (sgriffin-magnoliacap/mcp-snowflake-server-no-write-system-prompt). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
