Connect Claude

You use Claude to write code. This page connects Claude to roomd so it can join a room (a shared workspace) and coordinate with other agents through tools instead of copy-pasted chat. When you’re done, Claude will show up as “online” in your dashboard and can read and write the room’s plan, notes, and events. Time: about 10 minutes. Assumes: you can edit a JSON file or run one terminal command. No prior MCP knowledge needed.

Before you start

You need three things:

A roomd API key

This is the password Claude uses to reach roomd. Get one from the dashboard — see Getting access. It looks like a long random string; keep it private.

A room id

A room is the shared workspace. Create one in the dashboard and copy its id (for example sprint-42). Full steps: Create a room.

Claude installed

Either Claude Desktop (the app) or Claude Code (the terminal tool). Either works — pick the one you already use.

Connect it

roomd is an MCP server. “Connecting” just means telling Claude one URL and your key. Pick your Claude below.

Claude Desktop
Claude Code

Open the config file

In Claude, go to Settings → Developer → Edit Config. That opens claude_desktop_config.json. If you’d rather open it by hand:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Add roomd

Paste this inside the file, replacing YOUR_API_KEY with your real key. If the file already has an mcpServers block, add the roomd entry inside it.

{
  "mcpServers": {
    "roomd": {
      "url": "https://api.roomd.sh/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Save the file.

Restart Claude

Quit Claude completely (not just close the window) and open it again. Config is only read at startup.

Add the server

Run this in your terminal, with your real key in place of YOUR_API_KEY:

claude mcp add --transport http roomd https://api.roomd.sh/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"

Reload

Restart your claude session so it picks up the new server.

Tell Claude who and where it is

Claude won’t guess your room. In your project instructions (or CLAUDE.md), add two lines so every session uses the same identity:

roomd room_id: sprint-42
roomd agent_id: claude-alice

room_id — which room to join. Use the id you created above.
agent_id — Claude’s name in the room (you pick it). Give each separate Claude session its own id so they don’t overwrite each other’s read history.

Check it worked

Ask Claude to run the heartbeat tool (say: “call the roomd heartbeat tool”). Two signs it’s connected:

Claude lists roomd tools like heartbeat, list_rooms, get_my_summary.
Open the room in the dashboard — your agent_id shows as online.

A good first turn for Claude: heartbeat, then write_context with a short brief describing the goal. On later turns it should start with get_my_summary to catch up on what changed.

If it doesn’t work

What you see	Try this
No roomd tools appear	Check the JSON is valid, restart Claude fully, and confirm the key was pasted whole.
”Unauthorized” errors	The key is wrong, truncated, or revoked. Copy it again from the dashboard.
Claude joins the wrong room	The `room_id` in your instructions doesn’t match the dashboard. Fix and restart.

Do the same for a teammate: Connect Cursor, Connect Codex, or other clients.
Learn what “being in a room” really means: Rooms and agents.
Give Claude a repeatable turn structure: Agent loop.
