Who it's for: anyone with a Coworker account who uses Claude in the browser, the Claude desktop app, or Cowork. One connection covers all three.
Quickest way: open the Coworker MCP page for Claude in Coworker and follow the steps there. That page always has the latest steps, which can change when Claude updates its apps. The steps below are a backup.
Before you start: if your company's Claude admin already installed Coworker for everyone (see Install Coworker for your whole Claude organization), skip to step 3.
There are two ways. The plugin is recommended because it also brings Coworker's skills. If you don't see a Plugin tab on the Coworker page, use Option B.
Option A: Plugin (recommended)
In Coworker, open Settings and click Coworker MCP (or go to https://app.coworker.ai/links/intercom/settings/coworker-anywhere). Under Connect, stay on Connect yourself and pick Claude.
In claude.ai or the Claude desktop app, open Customize → Plugins. Install Coworker if your company published it. Otherwise click Download plugin (.zip) on the Coworker page, then in Claude click Add → Upload plugin and pick the zip.
Installing does not sign you in. In Customize → Plugins, open Coworker, go to its Connectors tab:
Connected: nothing to do
Not connected: click Connect and sign in to Coworker
Not added: click Add. If Claude asks for settings, use the ones in Option B step 2. Then click Connect.
Paste the instructions Coworker shows you into Settings → Your Claude → Instructions. Skip this if your admin set Organization instructions. This is what makes Claude reach for Coworker on company questions.
The first time Claude asks to use a Coworker tool, choose Always allow (in Cowork it's called Allow for all tasks).
Test it: in a new chat, paste
Coworker is connected. Show me what you know about my company and what I can ask you now.The Coworker MCP page switches to Connected once your request arrives. It checks for 5 minutes after the page loads and again when you come back to its window. If it still shows not connected, refresh it.
Option B: Manual connector
In claude.ai or the desktop app: Customize → Connectors → Add → Add custom connector. Name it
coworkerand pastehttps://odin.coworker.ai/mcp.Choose these settings and click Add:
Authentication: Sign in now
OAuth client: Register automatically. Don't keep the default, Use Claude's published identity (Recommended). Coworker doesn't accept it.
Request headers: leave empty
This dialog can look different depending on your organization.
Sign in to Coworker. If the sign-in doesn't open, click Connect on coworker.
Then follow Option A steps 4 to 6.
Common problems
"Coworker" is already in my connector list. Your admin added it. Just click Connect.
No Coworker tools in a chat. Click + in the message box (or type
/), open Connectors, turn coworker on, and finish sign-in if asked. Tools only show after sign-in completes.Claude asks permission on every request. Choose Always allow the next time it asks. In Cowork the option is Allow for all tasks. If it's grayed out, your Claude admin must turn on Allow "Always allow" for connector tools under Organization settings → Cowork (off by default).
"Unknown client" error when adding the connector. The connector was added with Use Claude's published identity (Recommended), which Coworker doesn't support yet. Delete the connector and add it again with Register automatically. Auth settings can't be edited after you click Add.
Can't add a connector at all (Team or Enterprise plan). An Owner may need to add Coworker for the org first (see Install Coworker for your whole Claude organization). Then connect with your own account.
