Two things slow down every freelancer who connects AI to their real infrastructure: getting the connection set up, and keeping it under control once it's live. This month's update tackles both — plus a new integration that helps you stay visible to clients without dropping everything to write content.
Here's what shipped in March.
TL;DR: March 2026 Update
- Quick Connect MCP Tools to Your AI — connect cloud-based AI clients (like Claude.ai) directly to your MCP server in seconds, no CLI or config files needed.
- The Right Tools for the Right People — define roles and restrict which tools each team member or partner can use.
- Ghost CMS Integration — jot down your notes, hand them to AI, and let it handle drafting and publishing while you stay focused on your work.
✨ What's New 🚀
MCP Express has always used OAuth under the hood — the same open authorization standard behind "Sign in with Google" or linking your accounting software to your bank. What's new is that MCP Express now supports AI client registrations through OAuth directly. Your AI client can register itself with MCP Express automatically, without you running a script or editing a config file to wire things together.
Paste the MCP Express gateway URL into your AI client's connector settings, complete the OAuth flow, and select which MCP server to expose. That's it. And because OAuth never passes your credentials directly through the connection — it issues scoped, revocable tokens instead — you're not trading convenience for security.

Set it up once in your AI client and it stays connected — from your laptop, your phone, anywhere. You're away from your desk and a client pings you about a production issue. Open Claude, ask it to check the logs, identify the failing query, and draft a fix. No reconnecting, no VPN, no SSH tunnel, no need to loop in someone else.
The CLI method isn't going anywhere
If you prefer setting up MCP connections through the CLI and a local config file, that workflow is still fully supported and won't be removed. OAuth is an additional option — use whichever fits your setup. You can find the CLI guide in our
step-by-step connection guide.
This one came out of our own internal use. As we connected more tools to MCP Express, we ran into a simple problem: not everyone working on a project should have access to everything. A contractor helping with support doesn't need visibility into your database. A client reviewing analytics doesn't need access to your deployment tools. We needed a way to draw those lines cleanly — so we built it.
Role-Based Access Control (RBAC) lets you define roles and assign each one a specific set of tools. Anyone assigned that role gets exactly what it allows — nothing more. It's the same access control model used across enterprise software, applied here at the tool level so you can share an MCP server without sharing everything on it.
In practice: you create a role, select which tools it can use, and assign it to whoever needs it. If you're bringing a support partner on board, you create a "Support Partner" role with access to your CRM and ticketing integrations only. They're up and running in minutes, with no risk of them touching anything they shouldn't. As your team or client roster grows, new people get onboarded with predefined roles — no more configuring access from scratch every time someone new comes in.
Tip
You can assign multiple roles to a single member and adjust them as your access model evolves. Start restrictive — it's easy to expand later.
✨ Integrations 🚀
Ghost CMS Integration
One of the hardest things about running a freelance business is staying visible while you're heads-down on client work. Writing blog posts, sharing expertise, keeping your profile active — it all matters, but it's the first thing that slips when a project gets busy.
The Ghost integration is built around a simple idea: you should be able to jot down your thoughts and let AI handle the rest. Drop your notes into a conversation, ask your AI to turn them into a structured post, and have it publish directly to Ghost — without ever opening the CMS. Your ideas stay yours. The formatting, structuring, and publishing becomes someone else's problem.
Connect your Ghost instance to MCP Express and your AI can list posts, retrieve drafts by slug, create new content, update existing posts, and publish — using the Ghost Admin API under the hood. Enable only the operations you want. If you'd rather keep your AI to read-only access for reviewing drafts, just leave the write operations off.
You'll need a Ghost Admin API key to connect. Generate one from your Ghost dashboard under Settings → Integrations → Add custom integration.
