UseMyContext is the personal context layer for AI. You keep one profile of who you are and what you are working on, plus the files that matter, owned by you at usemycontext.ai, and any MCP-capable AI client reads it. Sign in once and every AI you use already knows your context; you never re-introduce yourself, and you can see and revoke every connection from one page.

Try it in 30 seconds, no signup. The demo account works two ways: sign in on the web at usemycontext.ai (the "Try the live demo" button), or connect any MCP client to https://mcp.usemycontext.ai/mcp and use it at the OAuth sign-in. Login: demo@usemycontext.ai, code 424242 (fixed - no mailbox needed). A shared, read-only account with a full profile, files, and a shared context. Docs: usemycontext.ai/docs

The server is a standard remote MCP server:

https://mcp.usemycontext.ai/mcp

Streamable HTTP, OAuth 2.1. Any MCP-capable client can add it; sign-in is OAuth in the browser, no API key to copy. You need a UseMyContext account first - the free tier at usemycontext.ai is enough.

/plugin marketplace add usemycontext/claude-code-plugin
/plugin install usemycontext@usemycontext

Then run /mcp, select usemycontext, and complete the browser sign-in. The plugin adds a /umc skill and per-folder profile mapping; details in claude-code-plugin. Or skip the plugin and add the raw server:

claude mcp add --transport http usemycontext https://mcp.usemycontext.ai/mcp

Add to ~/.cursor/mcp.json (or .cursor/mcp.json in a project), then connect under Cursor Settings, Tools and MCP Servers:

{
  "mcpServers": {
    "usemycontext": {
      "url": "https://mcp.usemycontext.ai/mcp"
    }
  }
}

There is also a cursor-plugin with folder-to-profile mapping.

codex mcp add usemycontext --url https://mcp.usemycontext.ai/mcp
codex mcp login usemycontext

Or in ~/.codex/config.toml:

[mcp_servers.usemycontext]
url = "https://mcp.usemycontext.ai/mcp"

On older Codex versions, remote servers need experimental_use_rmcp_client = true under [features].

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "usemycontext": {
      "serverUrl": "https://mcp.usemycontext.ai/mcp"
    }
  }
}

Any client that speaks Streamable HTTP with OAuth can connect. The common JSON shape:

{
  "mcpServers": {
    "usemycontext": {
      "type": "http",
      "url": "https://mcp.usemycontext.ai/mcp"
    }
  }
}

Some clients name the fields differently (serverUrl, type: "streamable-http"); check your client's MCP docs for the exact key names.

Once connected, the client gets eight tools - profile, list_files, search_files, get_file, ask_docs, query_table, suggest_update, shared_context - all read-only against your files.

If your notes live in Notion, Google Drive, or Infomaniak kDrive, UseMyContext Premium can copy in the pages and files you pick, on your command. Your Notion notes become readable by every AI you use: Claude answers from them in the terminal, Cursor cites them in your editor, ChatGPT reads the same profile. Honest scope: this is Premium, it copies only what you explicitly pick, the connectors are read-only against your Notion and Drive, and disconnecting deletes the copies from our storage.

• Every read is scoped to a project you chose, and access leaves a record in your audit trail.
• One tool, suggest_update, can write: it files a pending suggestion that you review and approve in the web app. Nothing the AI does ever edits your profile or your files directly.
• Revoke any AI in one click, from /mcp in your client or the Connect page in the web app. Revoking is enforced on the server: the token dies immediately, everywhere.
• The free tier is enough to try all of this.
