ChatGPT reached 900 million weekly active users by February 2026 (DemandSage). With MCP support, those users can connect to external tools through a universal protocol — the same one that works with Claude, Cursor, and Windsurf. Here’s how to get started.
TL;DR
ChatGPT supports MCP via its Apps system (formerly “Connectors”). Enable Developer Mode in Settings, create a new app with your MCP server URL (e.g., https://openclaw.direct/mcp), and authorize via OAuth. Available for ChatGPT Pro, Team, Enterprise, and Edu plans. Setup takes under 3 minutes.
What You Need
Full MCP support including modify/write actions is in beta for ChatGPT Business, Enterprise, and Edu plans (OpenAI Help Center). You’ll need a ChatGPT account on one of these plans, plus an account on the MCP server you want to connect.
- ChatGPT Pro, Team, Enterprise, or Edu — Developer Mode isn’t available on Free or Plus plans
- An OpenClaw account — sign up free (the free tier supports full MCP access)

Enable Developer Mode
Developer Mode unlocks the ability to add custom MCP servers beyond OpenAI’s pre-built connectors like Google Workspace and Dropbox.
- Open Settings in ChatGPT
- Navigate to Connectors (or Apps)
- Open Advanced settings
- Toggle Developer Mode on
A word of caution: Developer Mode gives ChatGPT access to external tools that can read and write data. Only connect MCP servers you trust, and review tool calls before approving them — especially write operations.
Connect Your MCP Server
As of December 17, 2025, ChatGPT renamed “connectors” to “apps” (OpenAI Help Center). The functionality is identical — you may see either term depending on when your interface was last updated.
- In ChatGPT, go to Settings > Connectors (or Apps)
- Click Create
- Enter a name:
OpenClaw - Add a description:
Manage AI fleet instances via MCP - Paste the MCP server URL:
https://openclaw.direct/mcp - Click Save
ChatGPT will verify the connection and show the available tools from the MCP server. For OpenClaw, you’ll see 11 AI fleet management tools. The first time you use a tool, ChatGPT opens your browser for OAuth authorization — log in to OpenClaw and approve the connection.
OpenAI also provides pre-built connectors for popular services (Google Workspace, Dropbox, Slack) that don’t require Developer Mode. You can also connect Google Workspace to OpenClaw for integrated workflows. But for any custom MCP server — including OpenClaw — you need Developer Mode enabled.
Example Prompts to Try
Once connected, test the setup with these prompts:
- “Show me all my running AI instances” — calls
list_employees - “Check the health of my agents” — calls
employee_wellness_check - “What’s my billing status?” — calls
employee_timesheet - “Show available plans” — calls
list_plans
ChatGPT presents MCP tool results directly in the conversation. You’ll see both the raw data and ChatGPT’s interpretation. For more workflow inspiration, see 10 real-world MCP use cases.
ChatGPT vs Claude MCP: Key Differences
Both ChatGPT and Claude support MCP with the same tools and protocol. The server doesn’t care which client connects — OpenClaw’s 11 tools work identically on both. But the setup experience differs.
ChatGPT requires Developer Mode and uses a GUI-based “Apps” interface. Claude Desktop uses a JSON config file, and Claude Code uses a CLI command. ChatGPT restricts custom MCP to Pro/Team/Enterprise/Edu plans. Claude supports MCP on all plans, including free.
The key takeaway: MCP is cross-platform by design. Once your MCP server is running, it works with any compatible client — understanding the MCP server vs AI agent distinction helps clarify why. Pick the AI tool you prefer and connect — the experience on the server side is identical. For Claude-specific setup, see our Claude MCP setup guide.
Troubleshooting
Connection fails during setup: Verify that your MCP server URL is reachable over HTTPS. Try opening https://openclaw.direct/mcp directly in your browser — you should get a valid response, not a 404 or timeout.
OAuth re-authorization needed: If ChatGPT stops accessing your MCP server after it was previously working, the OAuth token may have expired. Go to Settings > Apps, find the connector, and re-authorize. This refreshes the access token.
Tools don’t appear: If the connector saves but shows no tools, check that Developer Mode is enabled. Without it, ChatGPT can’t discover custom MCP server capabilities.
Frequently Asked Questions
Can I use MCP with ChatGPT free or Plus?
Developer Mode for custom MCP servers requires ChatGPT Pro, Team, Enterprise, or Edu plans. OpenAI’s pre-built connectors (Google Workspace, Dropbox) are available more broadly. Check OpenAI’s latest plan details for current availability.
What’s the difference between a connector and an app in ChatGPT?
They’re the same thing. OpenAI renamed “connectors” to “apps” on December 17, 2025 (OpenAI Help Center). The setup process and functionality are identical. You may encounter both terms in documentation.
Is the MCP tool list the same in ChatGPT and Claude?
Yes. The MCP server exposes the same tools regardless of which client connects. OpenClaw’s 11 fleet management tools work identically in both ChatGPT and Claude. MCP is a standardized protocol — the server side doesn’t change based on the client, with 97 million monthly SDK downloads supporting this ecosystem (Pento, 2025).
Can ChatGPT write data via MCP?
Full MCP support including modify/write actions is rolling out in beta for ChatGPT Business, Enterprise, and Edu plans. Read-only tool calls are available more broadly. This is a ChatGPT-specific rollout timeline, not an MCP protocol limitation.
