Get table metadata (table/column schema) from Tsurugi RDBMS.
AI agents call getTableMetadata to retrieve information from Tsurugi Python Mcp Tools 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 of database metadata. It retrieves structural information about tables and columns without creating, modifying, deleting, or executing any code. The blast radius of misuse is minimal—an agent could only learn the database schema, which is a low-severity information disclosure risk. No side effects or irreversible actions are possible.
From the tool's definition getTableMetadata retrieves table and column schema information from Tsurugi RDBMS. The description explicitly states it 'Get[s] table metadata' with no modification, deletion, or execution of arbitrary operations.
Attacks that exploit this kind of access
Get table metadata (table/column schema) from Tsurugi RDBMS. It is categorised as a Read tool in the Tsurugi Python Mcp Tools MCP Server, which means it retrieves data without modifying state.
Register the Tsurugi Python Mcp Tools MCP server in PolicyLayer and add a rule for getTableMetadata: 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 Tsurugi Python Mcp Tools. Nothing to install.
getTableMetadata 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 getTableMetadata 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 getTableMetadata. 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.
getTableMetadata is provided by the Tsurugi Python Mcp Tools MCP server (septigram/tsurugi-python-mcp-tools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
