Get database (table) structure and data
AI agents call get_database to retrieve information from Wolai MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves database structure and data without creating, modifying, or deleting information. However, severity is rated 'medium' rather than 'low' because unauthorized access to database structure and data could enable reconnaissance for subsequent attacks, especially in a knowledge base system where data sensitivity varies.
From the tool's definition Tool name and description indicate 'Get database (table) structure and data' — a retrieval operation with no modification capability. This is fundamentally a read operation that queries database metadata and records.
Attacks that exploit this kind of access
Get database (table) structure and data. It is categorised as a Read tool in the Wolai MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Wolai MCP Server MCP server in PolicyLayer and add a rule for get_database: 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 Wolai MCP Server. Nothing to install.
get_database 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_database 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_database. 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_database is provided by the Wolai MCP Server MCP server (wuchaoli/wolai-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
