THE RISK

Low Risk

Why tailpipe_table_show needs a policy

tailpipe_table_show retrieves and displays metadata about a table structure (schema, columns, data types). This is a read-only operation with no side effects, no code execution, no data modification, and no destructive actions. The only risk is potential information disclosure of schema details, which is low severity in most contexts.

From the tool's definition Tool description states it 'Get detailed information about a specific Tailpipe table, including its schema, column definitions, data types, and descriptions.' This is purely informational retrieval with no modification, deletion, or execution of operations.

POLICY

How to control tailpipe_table_show

PolicyLayer is an MCP gateway — it sits between your AI agents and Tailpipe, and nothing reaches the server without passing your rules. This is the rule we recommend for tailpipe_table_show:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "tailpipe_table_show": {}
  }
}

tailpipe_table_show is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Tailpipe — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
