Remote vs Local MCP Servers: Which Should You Use?
Updated November 5, 2026
Short answer: A remote MCP server runs on someone else's computers and you connect to it with a URL. A local MCP server runs on your own machine. Choose remote for easy setup and web-based apps. Choose local when your data must stay on your computer or the server needs your files.
The main differences
| Remote | Local | |
|---|---|---|
| Setup | Paste a URL | Install and add a start command |
| Runs on | The provider's servers | Your computer |
| Connection | HTTP | Usually stdio |
| Sign-in | OAuth or API key | Environment variables, if any |
| Works in web apps | Yes | No, without a tunnel |
| Your data | Sent to the provider | Can stay on your machine |
| Updates | Handled by the provider | Up to you |
How common is each?
In our directory right now, 456 servers are hosted and 65 run locally. Of the hosted ones, 282 answer without sign-in, 161 require it and 13 are not responding. See the full MCP server statistics.
When should I choose remote?
- You use ChatGPT or Claude on the web.
- You don't want to install Node, Python or Docker.
- The server connects to an online service anyway, such as GitHub or Notion.
When should I choose local?
- The server needs your files, your apps or a device on your network.
- The data is private and must not leave your machine.
- You want full control over the version you run.
Is one safer than the other?
They carry different risks. A remote server sees whatever you send it. A local server runs code on your computer with your user's permissions. Read our safety guide before installing either.

Frequently asked questions
What is stdio in MCP?
stdio is how a local server talks to your app: the app starts the server as a program and they exchange messages through standard input and output, with no network involved.
Can a local MCP server work with ChatGPT?
Only through a tunnel. ChatGPT and Claude on the web connect to servers by URL, so a server on your computer isn't reachable otherwise.
