MCP guides
Hosting, auth and shipping for Model Context Protocol servers — written for people building real tools, not demos.
How to create an MCP server without writing code (2026)
Turn a plain-language description into a hosted, OAuth-protected MCP server — no SDK, no Docker, no TypeScript. What works, what the limits are, and when you still need code.
Connect a custom MCP server to Claude Desktop (step by step)
How to add a remote MCP server to Claude Desktop: the config snippet, the OAuth flow on first use, and a troubleshooting table for 401s, missing servers and invisible tools.
Add a custom MCP connector to ChatGPT (2026 guide)
How to connect a custom MCP server to ChatGPT: setup flow, the HTTPS and OAuth requirements, and the plan limits nobody mentions — write-capable connectors need a Business, Enterprise or Edu workspace.
Wrap any REST API as an MCP server
How to turn a REST API into an MCP server your AI clients can use: designing the tool surface (fewer, better tools beat 1:1 endpoint mapping), handling auth headers with encrypted secrets, and respecting upstream rate limits.
MCP server hosting: pricing & options compared (2026)
What hosting a remote MCP server actually costs in 2026 — Cloudflare Workers, Smithery, Composio, MintMCP and prompt-to-server generation, compared on price, effort and lock-in.
Composio alternative for bespoke MCP tools
Composio gives agents 1,000+ pre-built SaaS integrations. The gap is everything not in a catalog: your internal API, your database, your workflow. Here is the generate-your-own route — and where Composio clearly wins.
Smithery alternative: when you need hosting, not a directory
Smithery is the best-known MCP registry — thousands of servers, CLI install, hosting for listed servers. The gap: it assumes the server exists. Here is the route when it does not, and where Smithery clearly wins.
MCP transports explained: stdio vs SSE vs Streamable HTTP
What each MCP transport actually is, why the spec deprecated HTTP+SSE in favor of Streamable HTTP, and which transport to pick for local tools, remote servers and serverless deployments.
OAuth 2.1 for MCP servers: PKCE, DCR and RFC 8707 in plain English
The three RFCs behind MCP authorization — PKCE, Dynamic Client Registration and Resource Indicators — explained without jargon: what each one does, the full flow step by step, and what breaks when you skip one.
MCP server security checklist: secrets, isolation, auth
A practical security checklist for production MCP servers: transport auth, secret storage and injection, container isolation, least-privilege tool design, safe logging, and the prompt-injection surface of tool descriptions.
MCP Server ohne Code erstellen und hosten (2026)
Wie Sie ohne Programmierkenntnisse einen eigenen MCP Server erstellen und hosten: Tool auf Deutsch oder Englisch beschreiben, generierten TypeScript-Server mit OAuth 2.1 deployen, Install-Snippet in Claude, Cursor oder ChatGPT einfügen.
How to host a remote MCP server with OAuth (2026)
Streamable HTTP, OAuth 2.1, PKCE and Resource Indicators — what it actually takes to put a remote MCP server in production, and the shortcuts.
Hosted MCP platforms compared: Cloudflare, Smithery, Composio & generating your own
The MCP hosting landscape splits into four categories. Which one fits depends on whether you have a server already, need a catalog, or need bespoke logic.
MintMCP alternative: generate and host a custom MCP server
MintMCP wraps an existing STDIO server into a remote one. If you do not have a server yet, here is the generate-from-a-prompt route — and where MintMCP still wins.
