Get
AI agents call get_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 DDL (database schema definitions), which is a read-only operation with no side effects. It queries existing database structure without creating, modifying, or deleting data. While the description is minimal, the name and context strongly indicate a read operation. Low severity due to limited blast radius—DDL retrieval exposes schema information but cannot modify or destroy data.
From the tool's definition Tool name 'get_ddl' and description 'Get' indicate data retrieval. DDL (Data Definition Language) queries return schema structure without modification.
Attacks that exploit this kind of access
Get. 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_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_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_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_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_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.
