TL;DR: UseMyContext is one MCP server at https://mcp.usemycontext.ai/mcp (Streamable HTTP, OAuth). Every registry listing, plugin, and SDK below is a different door into that same server and the same account. Pick whichever fits the client you already use.
What is the one server behind all of this?
Everything on this page resolves to a single remote MCP server:
https://mcp.usemycontext.ai/mcpAny MCP client that supports Streamable HTTP can add that URL directly. Authentication is OAuth in your browser; no API key to paste. Every approved client shows up on the Connect page in your account, where you can revoke each one individually or disconnect everything at once.
Where is UseMyContext listed?
- The official MCP registry: published as
io.github.usemycontext/usemycontext- see the registry entry. The entry records the server name, the Streamable HTTP remote, and the source repository, so clients that sync from the registry can add it without any manual configuration. - Smithery: smithery.ai/servers/a-2yo0/usemycontext.
- mcp.so: submitted to mcp.so; the listing is currently in their review queue.
How do you install it in Claude Code or Cursor?
For Claude Code, the claude-code-plugin adds the server plus a folder-to-profile mapping skill, in two commands:
/plugin marketplace add usemycontext/claude-code-plugin
/plugin install usemycontext@usemycontextFor Cursor, use the cursor-plugin. And if you connect Claude on web or desktop instead, the step-by-step walkthrough is in How do I connect Claude to UseMyContext?
Can you connect from ChatGPT?
Yes, on paid ChatGPT plans: enable Developer Mode under Settings > Apps > Developer mode, then add the connector by URL with https://mcp.usemycontext.ai/mcp. The same OAuth approval and the same profile apply, and you ask for your profile or your documents exactly the way you would in Claude.
What if you are building your own app?
The usemycontext package on npm is a small SDK - a framework-free factory plus a React hook - wrapping all eight tools. Per-client config snippets and the plugin sources live on the UseMyContext GitHub profile.
FAQ
Is it the same account everywhere?
Yes. There is one profile and one server; every client above reads the same compiled context. On the Connect page you can revoke each client on its own, or disconnect everything at once when you want a clean slate.
Which listing should you trust?
Any of them. Whatever the directory, the server URL is always mcp.usemycontext.ai/mcp - if a listing points anywhere else, it is not us.
Is there a demo?
Yes: sign in as demo@usemycontext.ai with code 424242. It is a shared, read-only account, so you can browse a working profile before creating your own.
