Use this skill when building MCP (Model Context Protocol) servers with FastMCP in Python. FastMCP is a framework for creating servers that expose tools, resources, and prompts to LLMs like Claude. The skill covers server creation, tool/resource definitions, storage backends (memory/disk/Redis/DynamoDB), server lifespans, middleware system (8 built-in types), server composition (import/mount), OAuth Proxy, authentication patterns, icons, OpenAPI integration, client configuration, cloud deployment (FastMCP Cloud), error handling, and production patterns. It prevents 25+ common errors including storage misconfiguration, lifespan issues, middleware order errors, circular imports, module-level server issues, async/await confusion, OAuth security vulnerabilities, and cloud deployment failures. Includes templates for basic servers, storage backends, middleware, server composition, OAuth proxy, API integrations, testing, and self-contained production architectures.

Production-ready authentication framework for TypeScript with first-class Cloudflare D1 support. Use this skill when building auth systems as a self-hosted alternative to Clerk or Auth.js, particularly for Cloudflare Workers projects. Supports social providers (Google, GitHub, Microsoft, Apple), email/password, magic links, 2FA, passkeys, organizations, and RBAC. Prevents 10+ common authentication errors including session serialization issues, CORS misconfigurations, D1 adapter setup, social provider OAuth flows, and JWT token handling. Keywords: better-auth, authentication, cloudflare d1 auth, self-hosted auth, typescript auth, clerk alternative, auth.js alternative, social login, oauth providers, session management, jwt tokens, 2fa, two-factor, passkeys, webauthn, multi-tenant auth, organizations, teams, rbac, role-based access, google auth, github auth, microsoft auth, apple auth, magic links, email password, better-auth setup, session serialization error, cors auth, d1 adapter
Credential exposure detection, OAuth flow validation, API key management testing, and data sanitization verification for n8n workflows. Use when validating n8n workflow security.
Keycloak identity and access management including realms, clients, authentication flows, themes, and user federation. Activate for OAuth2, OIDC, SAML, SSO, identity providers, and authentication configuration.
Bootstrap new Hugo sites with Sveltia CMS and Basecoat UI, or convert existing sites (any SSG or CMS) to Hugo + Sveltia CMS. Use this skill whenever the user mentions Hugo, Sveltia CMS, Decap CMS migration, TinaCMS migration, static site CMS setup, headless CMS for Hugo, or wants to add a content management interface to a Hugo site. Also trigger when converting WordPress, Jekyll, Eleventy, TinaCMS, or other sites to Hugo, or when setting up Git-based content management. Covers the full workflow from scaffolding through Cloudflare Pages deployment with GitHub OAuth authentication.
Expo / React Native patterns with Clerk — SecureStore token cache, OAuth deep linking, useAuth in native, Expo Router protected routes, push notifications with user context. Triggers on: expo clerk, clerk react native, SecureStore token cache, expo router auth, OAuth deep link clerk, mobile auth clerk.
Develop Custom SCAPI endpoints for B2C Commerce. Use when creating REST APIs, defining api.json routes, writing schema.yaml (OAS 3.0), or building headless commerce integrations. Covers cartridge structure, endpoint implementation, and OAuth scope configuration.
Use skill if you are building or maintaining MCP servers with @modelcontextprotocol/sdk v1.x — single-package TypeScript SDK with Zod, RequestHandlerExtra, and built-in OAuth.
Self-hosted auth for TypeScript/Cloudflare Workers with social auth, 2FA, passkeys, organizations, RBAC, and 15+ plugins. Requires Drizzle ORM or Kysely for D1 (no direct adapter). Self-hosted alternative to Clerk/Auth.js. Use when: self-hosting auth on D1, building OAuth provider, multi-tenant SaaS, or troubleshooting D1 adapter errors, session caching, rate limits, Expo crashes, additionalFields bugs.
Build stateless MCP servers with TypeScript on Cloudflare Workers using @modelcontextprotocol/sdk. Provides patterns for tools, resources, prompts, and authentication (API keys, OAuth, Zero Trust). Use when exposing APIs to LLMs, integrating Cloudflare services (D1, KV, R2, Vectorize), or troubleshooting export syntax errors, unclosed transport leaks, or CORS misconfigurations.
Use this skill when building MCP (Model Context Protocol) servers with TypeScript on Cloudflare Workers. This skill provides production-tested patterns for implementing tools, resources, and prompts using the official @modelcontextprotocol/sdk. It prevents 10+ common errors including export syntax issues, schema validation failures, memory leaks from unclosed transports, CORS misconfigurations, and authentication vulnerabilities. This skill should be used when developers need stateless MCP servers for API integrations, external tool exposure, or serverless edge deployments. For stateful agents with WebSockets and persistent storage, consider the Cloudflare Agents SDK instead. Supports multiple authentication methods (API keys, OAuth, Zero Trust), Cloudflare service integrations (D1, KV, R2, Vectorize), and comprehensive testing strategies. Production tested with token savings of ~70% vs manual implementation.
