snowflake_describe_table
AI agents call snowflake_describe_table 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.
The 'describe' operation is a standard read-only SQL command that retrieves schema information (columns, types, constraints) from a Snowflake table. No side effects occur. While the description is empty (slightly lowering confidence), the name clearly indicates metadata retrieval. Snowflake's DESCRIBE TABLE command is fundamentally non-destructive and read-only, making this a Read category tool with low severity.
From the tool's definition Tool name 'snowflake_describe_table' indicates a describe/introspection operation, which retrieves metadata about table structure without modifying data.
Attacks that exploit this kind of access
snowflake_describe_table. 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_describe_table: 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_describe_table 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_describe_table 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_describe_table. 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_describe_table 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.
