Three Native Apps, Seamless Local Collaboration
No more tedious copy-pasting between chat windows and office suites
Watch AI Write Cell by Cell, Take Over Anytime
Hand messy text to your AI client, and watch it populate cells in real time. Take over manual edits whenever you want, and export XLSX files that render identically in WPS and Excel.
How AI Connects to InJoys Studio
Built on the open Model Context Protocol (MCP) to connect any client you prefer
1. Enable Local MCP Service
InJoys Studio includes a built-in MCP server, disabled by default. Enable it in Settings and generate a dedicated bearer token.
2. Loopback Address Security
Listens strictly on 127.0.0.1:17688. Not accessible from external networks. Each client uses its own token.
3. Configure Your AI Client
Add the endpoint to Codex CLI, DeepSeek Harness, TRAE, Qwen Code, or any MCP-compatible tool.

Technical Specifications
As a Public Beta build, the installer does not yet carry a commercial EV code-signing certificate. Windows displays an 'Unknown Publisher' warning. This is standard Windows behavior and does not affect safety.
Run this script in PowerShell to verify the checksum and ensure the installer is 100% authentic:
$expected = "37fc457b7f33a43dc67cfdeec7d5857653075df568a9d2741928326f318d77d0"
$actual = (Get-FileHash "$env:USERPROFILE\Downloads\InJoys-Studio_0.1.9_x64-setup.exe" -Algorithm SHA256).Hash.ToLower()
if ($actual -eq $expected) { "校验通过，可以安装" } else { "校验失败，请重新下载！" }Note: The installer is securely distributed over HTTPS from updates.injoys.ai.
