Common questions

Is The Margin safe?

It passed 2 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 35 days ago, and the latest version (1.0.0) reached the registry 41 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

The Margin

One place for work, home and your own plans, that works offline and that your AI can use.

Website · Try it, no account · Docs · Changelog · Discussions

What it is

The Margin keeps boards, notes, checklists, habits, money, meals, chores and chat in one app. A household or a team shares what it wants to share, and each person keeps a private side.

  • It works with no signal. A full copy of your data lives on the device and catches up when it is back online.
  • It has an assistant built in. Margin Intelligence can read across everything you keep there and act on it.
  • It works with the assistant you already use. Claude, ChatGPT, Grok, Cursor and any other MCP client can connect to your workspace, and each thing they add is marked with who added it.
  • Your data is yours. Export all of it whenever you like.

It runs in the browser and installs to a phone's home screen. Native apps for iPhone and Android are coming soon.

Connect your AI

The server is at https://mcp.themarginapp.com/mcp and speaks MCP over Streamable HTTP. Sign-in is OAuth 2.1, so most clients only need the URL.

ClientHow
ClaudeSettings → Connectors → Add custom connector, paste the URL
ChatGPTSettings → Apps & Connectors → Create, paste the URL
GrokSettings → Connectors → Add custom, paste the URL
Claude Codeclaude mcp add --transport http margin https://mcp.themarginapp.com/mcp
Cursor and other JSON-config clientsSee connector/examples

Menu names move around between releases of each client. If one of these is out of date, tell us.

Try it without an account

Point a client at https://mcp.themarginapp.com/sandbox/mcp with no credential. The server makes a demo household for that connection and deletes it about an hour after your last call.

claude mcp add --transport http margin-sandbox https://mcp.themarginapp.com/sandbox/mcp
What an assistant can do

271 tools. 112 only read, 82 add or change, 77 can remove or overwrite. Every one is scoped to the person who signed in and the workspaces they chose.

The full list is in connector/TOOLS.md, with input schemas in connector/tools.json. The guide is at themarginapp.com/docs/agents-and-mcp.
