Get the full DDL of a stored procedure or function
AI agents call get_routine_ddl to retrieve information from Querybridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves the textual definition of a stored procedure or function, analogous to querying the information_schema or using SHOW CREATE PROCEDURE. This is a read operation with no side effects, no code execution, and no data modification. While the retrieved DDL could theoretically contain malicious code if examined by an agent, the tool itself only retrieves and does not execute the routine.
From the tool's definition Tool name and description indicate retrieval of DDL (Data Definition Language): 'Get the full DDL of a stored procedure or function'. DDL retrieval is a read-only operation that queries metadata without modifying or executing code.
Attacks that exploit this kind of access
Get the full DDL of a stored procedure or function. It is categorised as a Read tool in the Querybridge MCP Server, which means it retrieves data without modifying state.
Register the Querybridge MCP server in PolicyLayer and add a rule for get_routine_ddl: 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 Querybridge. Nothing to install.
get_routine_ddl 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_routine_ddl 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_routine_ddl. 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_routine_ddl is provided by the Querybridge MCP server (mahmoudhassanmustafa/querybridge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
