UseMyContext plugin marketplace for Cursor

Your personal context layer for AI follows you into your editor. This repository is a Cursor plugin marketplace that distributes the UseMyContext plugin: sign in once and Cursor reads your UseMyContext profile, lists and opens your files, and answers from your documents, all read-only against your files and audited. 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, and every read is logged to your audit trail. Map a folder to one of your projects and every session in that folder reads the right context.

Install

Once this plugin is listed in Cursor's marketplace, add it from cursor.com/marketplace (the "Add to Cursor" button) or with /add-plugin in the editor, then open Cursor Settings, go to Tools and MCP Servers, find usemycontext, and click Connect to complete the browser sign-in. Full plugin docs, including how folder-to-profile mapping works, are in plugins/usemycontext/README.md.

Try it in 30 seconds

No signup needed. At the browser sign-in, use demo@usemycontext.ai with code 424242 (fixed - no email access needed). A shared, read-only demo account with a full profile, files, and a shared context. Then ask Cursor "what do you know about me?". Docs: usemycontext.ai/docs

What it can and cannot do

• Reads: your profile and the files you uploaded to UseMyContext, scoped to the connected or mapped project.
• Writes: nothing to your files. The one write tool, suggest_update, files a pending suggestion that you review and approve in the web app.
• Every read is logged to your audit trail.
• You can revoke access at any time: disconnect usemycontext under Cursor Settings, Tools and MCP Servers, or revoke from the Connect page in the UseMyContext web app. Revoking is enforced on the server: the token dies immediately, everywhere.
• It does not change your Cursor account, your Cursor plan, your billing, or which model runs.

Publishing

Cursor plugins are distributed as Git repositories and every plugin is manually reviewed by the Cursor team before it is listed. Before committing a change, validate the format:

node scripts/validate.mjs

Fix every reported error. This checks the manifests parse, the plugin name is lowercase kebab-case, the marketplace entry maps to a real folder, referenced paths (logo, hooks, mcp) resolve, and skill and rule files carry their required frontmatter. Bump version in plugins/usemycontext/.cursor-plugin/plugin.json on every release. Nothing here deploys a worker or a Pages site; the plugin only needs this public repository to exist. The live UseMyContext service it connects to is at usemycontext.ai.
