Preferred path: run /agentstack:login after installing the plugin. It walks through OAuth Device Code and then configures Claude Code with:
claude mcp add agentstack --transport http https://agentstack.tech/mcp \
--header "Authorization: Bearer <access_token>" \
--header "Content-Type: application/json"Fallback path: create an anonymous project/API key and configure:
claude mcp add agentstack --transport http https://agentstack.tech/mcp \
--header "X-API-Key: <agentstack_api_key>" \
--header "Content-Type: application/json"Verify with:
claude mcp list
