Get the full CREATE TABLE definition for a table
AI agents call get_table_definition to retrieve information from SQL Server 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 table schema metadata (the CREATE TABLE definition) with no side effects. It performs introspection only, similar to INFORMATION_SCHEMA queries or DESCRIBE commands, which are non-destructive read operations. The read-only nature of the server and the informational purpose of the tool confirm this classification.
From the tool's definition Tool name 'get_table_definition' and description 'Get the full CREATE TABLE definition for a table' indicate retrieval of metadata without modification.
Attacks that exploit this kind of access
Get the full CREATE TABLE definition for a table. It is categorised as a Read tool in the SQL Server MCP MCP Server, which means it retrieves data without modifying state.
Register the SQL Server MCP server in PolicyLayer and add a rule for get_table_definition: 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 SQL Server MCP. Nothing to install.
get_table_definition 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 get_table_definition 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 get_table_definition. 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.
get_table_definition is provided by the SQL Server MCP server (millelog/sql-server-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
