Claude Code SpacePost send_broadcast

How to: Claude Code SpacePost send_broadcast

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

Add SpacePost to Claude Code

  1. 01

    Run this in your project directory.

claude mcp add --transport http mcp https://api.spacepost.dev/mcp
  1. 02

    Restart your session so the server is picked up.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that SpacePost'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

Set these first

SpacePost will not start until these are set, so send_broadcast never becomes available.

  • SPACEPOST_API_KEY
  • SPACEPOST_READ_ONLY
  • SPACEPOST_TOOLSETS
  • SPACEPOST_PERMISSION
  • SPACEPOST_DEFAULT_FROM

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 11 November 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.
