**Note:** The **category** is auto-populated if selected in the last modal.

Field	Description
REST API	Select a REST API type from the list.
Label	An internal name for the tool.
MCP app	An active MCP app linked to this REST API.
Description	The description of what the tool intends to do. This input is exposed to AI clients and used to determine when to call this tool. Note: Admins must add specific and action-oriented description as the AI clients access it to decide when to invoke the tool.
MCP Servers	One or more servers you want to add your tool to.

In the Tool inputs section, the fields associated with the capability are added. See [Create a tool for a Model Context Protocol server](create-tool-mcp-server.md) to learn more. The tool is now published on the MCP Server and discoverable by MCP clients.
