Get table size information (size, row count)
AI agents call get_table_size to retrieve information from Mcp Database without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query to obtain table metadata. It does not create, modify, delete, or execute arbitrary operations. The blast radius if misused is minimal—an AI agent could only gather database structure information. No data modification or system commands are possible.
From the tool's definition The tool description states it retrieves 'table size information (size, row count)'. These are metadata queries with no modification, deletion, or execution of code.
Attacks that exploit this kind of access
Get table size information (size, row count). It is categorised as a Read tool in the Mcp Database MCP Server, which means it retrieves data without modifying state.
Register the Mcp Database MCP server in PolicyLayer and add a rule for get_table_size: 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 Mcp Database. Nothing to install.
get_table_size 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_size 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_size. 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_size is provided by the Mcp Database MCP server (nam088/mcp-database-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
