Get the total number of rows in a table
AI agents call get_table_count to retrieve information from Enhanced MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read operation that queries table statistics. It has no side effects, does not modify data, does not execute code or commands, and does not delete or move resources. The blast radius of misuse is minimal—an agent could at worst retrieve metadata about table sizes, which poses no integrity or availability risk to the underlying data.
From the tool's definition Tool name is 'get_table_count' and description states 'Get the total number of rows in a table' — a pure query operation that retrieves aggregate metadata without modifying, executing external commands, or deleting data.
Attacks that exploit this kind of access
Get the total number of rows in a table. It is categorised as a Read tool in the Enhanced MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Enhanced MCP Server MCP server in PolicyLayer and add a rule for get_table_count: 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 Enhanced MCP Server. Nothing to install.
get_table_count 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_count 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_count. 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_count is provided by the Enhanced MCP Server MCP server (pbulbule13/mcpwithgoogle). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
