Local vs Remote MCP Servers

Not all MCP servers work the same way. Some run on your machine; others live in the cloud. Understanding the difference helps you pick the right server for your needs.

Local servers

Run as a process on your own machine. You install them via npx, pip, or similar, and they communicate with your AI client over a local socket.

  • Data stays on your machine
  • Works offline
  • Full control over the server code
  • Requires setup per machine
  • You manage updates
  • Harder to share with a team

Remote servers

Hosted in the cloud by the server operator. You connect by adding a URL to your config — no local install, no runtime to manage.

  • Zero local setup
  • Easy to share across a team
  • Operator manages updates
  • Requires internet connection
  • Data travels to third-party server
  • Depends on operator uptime

When to choose local

Choose a local server when you're working with sensitive data — internal databases, private code repositories, personal files, or anything subject to compliance requirements like GDPR or HIPAA. With a local server, your data never leaves your machine, so you don't need to trust a third-party host.

Local servers are also the better choice for individual developers who are comfortable with a terminal and want fine-grained control over what the server can and cannot access.

When to choose remote

Remote servers shine in team environments. Instead of every team member running their own local instance and staying in sync on updates, everyone connects to the same hosted endpoint. This is especially useful for customer-facing tools or internal knowledge bases where consistency matters.

Remote servers are also the easier option for non-technical users. If someone in your organisation wants to use an MCP-powered workflow but isn't comfortable installing Node.js, a remote server removes that barrier entirely.

Authentication on remote servers

Remote MCP servers use one of three authentication methods:

OAuth — You log in with an existing account (e.g., Google or GitHub). The most user-friendly option and the least likely to expose credentials.
API key — You generate a key in the service's dashboard and paste it into your config. Simple, but you're responsible for keeping the key secret.
Open access — No credentials required. Suitable for public data sources with no rate limit concerns.
