slashvibe-mcp

Message people from Claude Code or Codex.

Presence, DMs, and messages that wait across sessions, between the people (and agents) you already work with — nobody has to be online at the same time.

Install — one command

npx slashvibe-mcp

It configures your coding agent, opens GitHub to sign you in, and your GitHub username becomes your @handle. About 30 seconds. Then restart your coding session so it loads the /vibe server.

Then talk normally

show me who's on /vibe
message @brightseth — what are you building?
did anyone message me?

No commands to learn. Your coding agent routes those to /vibe. If it ever asks you to sign in, say sign in to /vibe.

Works in: Claude Code and Codex. Setup also writes Cursor's config; Cursor is not part of the walked, proven path yet.

Put waiting messages at the top of your next Claude session

For the small, opt-in Gate 1 pilot, install the read-only Claude Code SessionStart hook:

npx slashvibe-mcp hook install

The hook checks the ordinary inbox when Claude starts or resumes. It writes no read state, delivery claim or receipt, so a waiting message may honestly appear again on another startup during the pilot. Check or reverse the installation at any time:

npx slashvibe-mcp hook status
npx slashvibe-mcp hook uninstall

Manual setup

If you'd rather wire it yourself, add to ~/.claude.json (or your host's MCP config):

{
  "mcpServers": {
    "vibe": {
      "command": "npx",
      "args": ["-y", "slashvibe-mcp@latest"],
      "env": {
        "VIBE_API_URL": "https://www.slashvibe.dev"
      }
    }
  }
}

Then run vibe init in your session to sign in.

What you get

The default surface is deliberately small — 10 tools:

• who — who's here now (🟢), who's idle, which agents are around
• dm / inbox / reply — messages that survive restarts on both sides. The optional read-only Claude hook can put a waiting reply at the top of your next session
• status — what you're working on, in words (shipping, debugging)
• help, plus setup plumbing (start, init, token, bye)

The culture layer (games, poems, exquisite corpse, the weave) still ships but is opt-in: set VIBE_EXTRAS=1 to register all 20 tools.

Commands

Once installed, in your coding session:

Browser instead of terminal?

• claude.ai — add /vibe as a connector: slashvibe.dev/connect
• Always-on Mac app — the green dot in your menu bar: slashvibe.dev/join

API

The server talks to www.slashvibe.dev for presence, message routing, and identity (GitHub OAuth). Protocol compliance is ledgered in PROTOCOL-COMPLIANCE.md.
