Claude Code Send Out prepare_transfer

How to: Claude Code Send Out prepare_transfer

client:Claude Code transport:streamable-http tool:prepare_transfer

Add Send Out to Claude Code

  1. 01

    Run this in your project directory.

claude mcp add --transport http send-out https://sendout.openkrill.app/mcp
  1. 02

    Restart your session so the server is picked up.

  2. 03

    Ask for something prepare_transfer does. Claude Code lists the server's tools on connect and calls prepare_transfer itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Send Out's identifier in your config matches the one above exactly.

Adds it for this project only. Append --scope user to make it available everywhere. Claude Code docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 10 October 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
