Keyless Cursor Enhancement Plugin · Infinity Assistant, forked and enhanced based on a78789191888/wkmcp-pjb. While retaining all its sidebar multi-session MCP functionality, it includes a built-in Cursor Membership Switcher (independent page, click to navigate; ported from the original Cursor Membership Switcher project).

This plugin no longer relies on any keys/activation codes/trial periods; it is ready to use upon opening.

Features

1. Sidebar Multi-Session MCP (Retained from wkmcp)

• Multi-project, multi-window parallel processing: Up to 32 sessions (my-mcp-1 … my-mcp-32), each bound to an independent message channel.

• Three MCP tools: check_messages / send_message / ask_question, supporting attachments (images/file base64).

• One-click "Start Configuration" to write the current sidebar session list to the workspace .cursor/mcp.json.

• Session memos, voice input (Windows), and persistent chat history.

2. Cursor Membership Switcher (Independent Page)

• Independent Settings Page: The sidebar only keeps an entry button; clicking it opens the full settings page in the editor area (no longer occupying sidebar space).

• Automatic detection of Cursor installation path (running processes + common directories).

• One-click membership type switching: Free / Free Trial / Pro / Pro+ / Ultra / Enterprise, also supports custom strings.

• Automatic backup of original files, with one-click restoration at any time.

• Automatically prompts to close running Cursor instances before applying patches.

• One-click Cursor restart.

3. Cursor Billing and Usage (New, Independent Page)

• Independent Billing Page: Adds an "Open Billing and Usage" button to the sidebar, opening in the editor area.

• Automatic reading of local state.vscdb: Directly retrieves the currently logged-in Cursor account via cursorAuth/accessToken (no pasting required).

• First installation → Local records: Prioritizes parsing composerData:* in cursorDiskKV, estimating historical tokens using approximate character weights for quick display.

• Subsequent times → Official API: Marks hasFetchedFromApi after a hit, no longer falling back to local cache.

• Cursor APIs called (referencing Open Switch implementation and tokscale):

  • POST https://api2.cursor.sh/aiserver.v1.AuthService/GetUserMeta

  • GET https://api2.cursor.sh/auth/full_stripe_profile

  • GET https://cursor.com/api/usage-summary

  • GET https://cursor.com/api/dashboard/export-usage-events-csv?strategy=tokens

• Displayed Content:

  • Account Info Card: Email, membership type, subscription status, WorkOS ID.

  • Overview KPI Card: Today / This Week / This Month / Total $ consumption + token count + request count.

  • Last 30 days daily consumption bar chart (pure SVG, no chart library dependency).

  • Model breakdown table: Requests / Input / Output / Cache Read/Write / Total Tokens / Consumption $.

• Data Source Labeling: A badge at the top of the page clearly indicates whether the current data is from Cursor API (Real-time) / Local composerData (Approximate) / Local Cache.

• Implementation details:

  • Uses embedded sql.js (pre-packaged wasm, approx. 690 KB) to read state.vscdb, copying to Buffer in read-only mode without locking Cursor.

  • Uses Node's built-in https to call APIs, with no other npm runtime dependencies.

  • Automatically retries once on API failure (TLS / socket jitter tolerance).

Build and Packaging

Environment Requirements

• Node.js 18+ (requires npm)

• Windows / macOS / Linux are all supported; PowerShell is recommended for Windows.

• No need to install vsce globally; it is pulled as a devDependencies with the package (@vscode/vsce).

One-Click Packaging

npm install          # 安装根依赖 + 触发 postinstall 安装 mcp-server 子包依赖
npm run compile      # 1) tsc -p . 编译 src/ → dist/   2) 执行 scripts/copy-vendor.js
npm run package      # 等价于 compile + vsce package --no-dependencies --allow-missing-repository

After successful packaging, you will get the following in the root directory of the repository:

cursor-free-plus-1.4.0.vsix   （版本号取自 package.json 的 "version"）

Usage

1. After installation, the Infinity Assistant icon will appear in the left activity bar; click it to open the sidebar.

2. Fill in the workspace path or select "Use Current", then click "Start Configuration" to write to .cursor/mcp.json.

3. Click the "Cursor Membership Type → Open Membership Type Settings" button, select the type on the new page, and click "Apply Patch".

4. After the patch is complete, click "Restart Cursor" to apply the changes.
