ChatGPT can now connect to external tools and data sources through MCP — the Model Context Protocol. If you've seen "MCP" mentioned and weren't sure what it means or how to actually use it in ChatGPT, this is a plain-English explainer: what MCP is, how to enable it, how to add a ChatGPT MCP server, and a real working example at the end.
What MCP actually is
MCP (Model Context Protocol) is an open standard, originally introduced by Anthropic, that lets AI assistants connect to outside data and tools in a consistent way. Instead of every service building a custom integration for every AI assistant, MCP gives them one shared protocol. The result: you can plug a data source into an AI by adding a single connector URL, and the AI can then read from it, query it, or act on it.
It's often described as a USB-C port for AI — one standard connection that many different tools can use.
A ChatGPT MCP server is the piece that sits between ChatGPT and a data source. It exposes specific tools — like "get recent activities", "search documents", or "query a database" — that ChatGPT can call during a conversation. Any service that runs an MCP server with an HTTPS URL can be connected to ChatGPT this way.
ChatGPT and MCP: what you need to know
ChatGPT supports MCP connectors through Developer Mode, currently in beta. Once you've enabled it, you can add any remote MCP server by pasting its URL, and the tools that server exposes become available inside your conversations — ChatGPT calls them automatically when relevant.
A few things to know before you start:
- Developer Mode may depend on your ChatGPT plan and OpenAI's current rollout — check Settings → Apps & Connectors to see if it's available to you.
- When you add a custom connector, ChatGPT shows a warning that it's unverified. This is standard for any third-party MCP server, since the connector can read data on your behalf.
- ChatGPT MCP servers must use a secure HTTPS URL — plain HTTP won't work.
- Connectors are tied to your account. Other users can't access your data through yours.
How to enable Developer Mode in ChatGPT for MCP
Developer Mode is the gateway to MCP connectors in ChatGPT. Here's how to turn it on:
- Open ChatGPT and go to Settings.
- Find Apps & Connectors, then open Advanced settings.
- Toggle Developer Mode on. ChatGPT will show a confirmation prompt — accept it.
Once Developer Mode is active, a new option to add connectors appears in the Apps & Connectors section. You only need to do this once.
How to add an MCP connector to ChatGPT
With Developer Mode enabled, adding a ChatGPT MCP server takes about a minute:
- Go to Settings → Apps & Connectors.
- Choose to add a new connector.
- Give it a name (anything descriptive works) and paste the HTTPS URL of the MCP server.
- Confirm. The connector is now active in your account.
To use it, open any chat and ask something the connector can answer. ChatGPT calls the relevant tools automatically — you don't need to trigger anything manually, just ask in plain language.
Tip: the first time ChatGPT uses a connector in a conversation, it may ask you to confirm. If your account offers an option to allow it to run without asking each time, enabling that makes the experience much smoother.
A real example: connecting Strava to ChatGPT via MCP
A practical way to see ChatGPT MCP in action is connecting your own data. Take Strava: with a Strava MCP server added as a connector, you can ask ChatGPT things like "How many km did I run last week?", "Am I overtraining this month?", or "Summarize my last long ride" — and it answers from your real activities, not generic advice.
That's exactly what AskYourData built: a hosted Strava MCP server that handles all the technical setup. Instead of running your own server, you connect your Strava account and paste one URL into ChatGPT as a connector. It also works with Claude — one subscription covers both assistants.
The experience feels different from a normal AI chat because ChatGPT already has your full training history in context. You're not copying numbers into a prompt or describing your last workout — you're just asking, and it already knows.
For the full step-by-step on this specific integration, see our guide on how to connect Strava to ChatGPT. The same connector also works with Claude.
Frequently asked questions
Does ChatGPT support MCP?
Yes. ChatGPT supports MCP connectors through Developer Mode, currently in beta. Once enabled in Settings → Apps & Connectors, you can add any remote MCP server by URL and use its tools in your conversations.
What is a ChatGPT MCP server?
A ChatGPT MCP server is an HTTPS endpoint that exposes tools ChatGPT can call — for example, reading your Strava activities, querying a database, or fetching documents. You add it to ChatGPT by pasting its URL when creating a new connector.
Do I need a paid ChatGPT plan to use MCP connectors?
Developer Mode and MCP connector support may require a paid ChatGPT subscription, depending on OpenAI's current rollout. Check Settings → Apps & Connectors in your account to see if the option is available to you.
Can I connect Strava to ChatGPT using MCP?
Yes. With a Strava MCP server added as a ChatGPT connector, ChatGPT can read your real Strava activities and answer questions about your training. AskYourData provides a hosted Strava MCP server — you paste one URL and you're done, no server setup required.
