# Fix: tools/list returns a tools array with input schemas

> Web-audit fix skill for the `mcp-tools-list` check (MCP & API, MUST).

## Goal

Return tools/list entries with name, description, and a JSON inputSchema.

## Fix

Return `result.tools` as an array from the `tools/list` method. Each tool needs a `name`, a
`description`, and a JSON Schema `inputSchema` so an agent can validate arguments before
calling. A tool without an `inputSchema` forces the agent to guess argument shapes.
