Who it's for: developers using Claude Code in the terminal. The plugin needs Claude Code v2.1.224 or later.
Quickest way: open the Coworker MCP page for Claude Code in Coworker and follow the steps there. That page always has the latest steps, which can change when Claude Code updates. The steps below are a backup.
If your admin pushed Coworker to everyone: nothing to install. Run /mcp to check it is there, then go to step 3. If you sign in to Claude Code with your claude.ai account, a connector added in claude.ai also shows up there automatically. It doesn't if you use an API key.
Install the plugin. In Claude Code run:
/plugin marketplace add https://app.coworker.ai/plugin/marketplace.jsonthen/plugin install coworker@coworker(Prefer no plugin? Runclaude mcp add --transport http coworker https://odin.coworker.ai/mcpand paste the instruction text from the Coworker MCP page into~/.claude/CLAUDE.md.)Sign in once: run
/mcp, select coworker, and sign in to Coworker in the browser. Or runclaude mcp login coworkerfrom your shell. The token is saved.Stop the approval prompts: run
/permissionsand addmcp__plugin_coworker_coworker__*to the allow list, or choose "don't ask again" the first time each tool asks. If you connected without the plugin, allowmcp__coworkerinstead.
For admins (whole team): Coworker MCP page → Install for your Claude org → Claude Code card → Copy managed settings, then paste into claude.ai Organization settings → Claude Code → Managed settings and save. Every developer gets Coworker at next login and signs in once per machine. Server push needs Claude Code v2.1.259 or later.
Common problems
Tools not showing. Run
/mcpto see whether coworker is listed and signed in.Prompted on every call. Step 3 wasn't done, or the pattern doesn't match how you connected (plugin vs direct).
