ChatGPT MCP Server Setup Guide

This guide walks through connecting ChatGPT to the Hudu MCP (Model Context Protocol) Server.

Once connected, ChatGPT can interact directly with your Hudu instance to:

Read documentation
Create articles
Update articles
Review activity logs
Assist with documentation workflows

Requirements

Before starting:

MCP access must already be enabled in Hudu
Your Hudu instance should be accessible over HTTPS/SSL
You must have access to ChatGPT Apps/Developer Mode

Your MCP endpoint will typically look like:

https://yourhuduinstance.com/mcp

Enable MCP in Hudu First

Inside Hudu:

Navigate to:

Admin → External Apps → Model Context Protocol (MCP)

Enable MCP access if it is not already enabled.
Confirm your MCP endpoint URL.

Setup in ChatGPT

Step 1. Open ChatGPT Settings

Inside ChatGPT:

Click into your profile
Click Settings
Open Apps
Enable Developer Mode

Depending on your environment, you may see warnings about unverified apps. This is expected for privately hosted MCP servers.

Step 2. Create a New App

Click Create App
Enter:
- App Name
- Description
- MCP Server URL

Example:

https://yourhuduinstance.com/mcp

Step 3. Configure OAuth

Select OAuth authentication
Continue through the warning prompts
Click Create

ChatGPT will now attempt to connect to your Hudu MCP server.

Step 4. Authenticate with Hudu

After the app is created:

A Hudu OAuth login window will appear
Sign in to Hudu
Approve the requested permissions

Once approved, ChatGPT will automatically discover the available Hudu MCP tools.

OAuth Authorization

When connecting to the Hudu MCP server for the first time, Hudu will display an OAuth authorization screen asking the user to approve the connection.

The authorization request includes the required permissions (scopes), including:

Read access
Write access

Users must approve the requested scopes before the MCP connection can be established successfully.

Verifying the Connection

After authentication:

ChatGPT should display available Hudu tools
You can begin interacting with Hudu using natural language prompts

Example prompts:

“Create a draft SOP for workstation onboarding”
“Find documentation related to backup failures”
“Summarize recent documentation changes”
“Update this article with the latest firewall procedure”
