Building an Agent MCP Server
Scalekit lets you build MCP servers that manage authentication, create personalized access URLs for users, and define which tools are accessible. You can also bundle several toolkits (e.g., Gmail + Google Calendar) within a single server.
Model Context Protocol (MCP) is an open-source standard that enables AI systems to interface with external tools and data sources. Where the integrating-agent-auth skill uses the SDK directly, this workflow exposes Scalekit tools over the MCP protocol so any compliant client — LangChain, Claude Desktop, MCP Inspector — can consume them.
Note: Agent Auth MCP servers only support Streamable HTTP transport.
What you'll build
- A Scalekit MCP server that fetches the user's latest email and creates a reminder calendar event
- A LangGraph agent that connects to this server via
langchain-mcp-adaptersand invokes the tools
Prerequisites
- Scalekit credentials: app.scalekit.com → Settings → Copy
SCALEKIT_CLIENT_ID,SCALEKIT_CLIENT_SECRET,SCALEKIT_ENV_URL - OpenAI API key:
OPENAI_API_KEY
Gmail is the only connector that does not require dashboard setup. All other connectors (including Google Calendar) must be created in the Scalekit Dashboard before use:

setup-scalekit
Use when a developer is new to Scalekit and needs guidance on where to start, doesn't know which auth plugin or skill to choose, wants to connect an AI agent or agentic workflow to third-party services (Gmail, Slack, Notion, Google Calendar), needs OAuth or tool-calling auth for agents, wants to add authentication to a project but hasn't chosen an approach yet, or needs to install the Scalekit plugin for their AI coding tool (Claude Code, Codex, Copilot CLI, Cursor, or other agents).
11integrating-agent-auth
Integrates Scalekit Agent Auth into a project to handle OAuth flows, token storage, and automatic refresh for third-party services (Gmail, Slack, Notion, Calendar). Use when a user needs to connect to an external service, authorize OAuth access, fetch access or refresh tokens, or execute API calls on behalf of a user.
5implementing-scalekit-fsa
Implements Scalekit full-stack authentication (FSA) including sign-up, login, logout, and secure session management using JWT tokens. Use when building or integrating user authentication with the Scalekit SDK across Node.js, Python, Go, or Java — or when the user asks about auth flows, OAuth callbacks, token refresh, or session handling with Scalekit.
4adding-mcp-oauth
Guides users through adding OAuth 2.1 authorization to Model Context Protocol (MCP) servers using Scalekit. Use when setting up MCP servers, implementing authentication for AI hosts like Claude Desktop, Cursor, or VS Code, or when users mention MCP security, OAuth, or Scalekit integration.
3modular-sso
Implements complete SSO and authentication flows using Scalekit. Handles modular SSO, IdP-initiated login, user session management, and enterprise customer onboarding. Use when adding authentication, SSO, SAML, OIDC, or user login to applications.
3sk-actions-custom-provider
Create or review Scalekit custom providers/connectors for proxy-only usage. Use this skill when the task is to gather API docs, infer whether a connector is OAuth, Basic, Bearer, or API Key, determine required tracked fields like domain or version, generate provider JSON, check for existing custom providers, show update diffs, run approved create or update curls, and print resolved delete curls.
