CrewAI lets you split complex workflows across specialized agents, but each agent still needs authenticated access to user tools like Gmail. This cookbook shows how to wire Scalekit OAuth into a CrewAI crew via MCP, then build a three-agent pipeline that scans, classifies, and drafts replies to a user’s unread emails.
The Next.js App Router runs auth on the server, but Scalekit’s framework-agnostic guides assume Express-style request and response objects. This cookbook maps the full hosted-login flow — redirect, code exchange, session cookies, refresh, and logout — onto Route Handlers, Server Components, and middleware.
B2B billing breaks when your auth org model and Chargebee customer records drift apart. This cookbook shows how to use the Scalekit organization ID as the billing reference, provision Chargebee customers on org creation, run hosted checkout, and reconcile subscription state from Chargebee webhooks.
Connect FastRouter’s OpenAI-compatible API to per-user OAuth tools via Scalekit. The agent discovers available tools, runs an agentic loop through FastRouter, and executes each tool call via Scalekit — no per-integration OAuth code required.
Mastra agents need tools. Each third-party API — Gmail, Slack, Calendar — means another OAuth flow, another token store, another refresh cycle. This recipe connects a Mastra agent to Scalekit AgentKit tools using the Node SDK, with automatic authorization and token refresh.
