ToolBraid combines a WebMCP-enabled browser extension and a local Windows companion. Connect it to your existing Codex session or another MCP client, or use the optional ChatGPT side-panel chat. Your assistant can work with real pages, desktop controls, approved files and repeatable workflows.
This is the official source, releases and documentation repository for the public edition. The browser extension, Windows companion, tests and packaging scripts are available under Apache 2.0.
Updated 14 October 2026: 0.4.0 adds project access profiles, reviewable bug reports, native WebMCP test scenarios, incremental page context and a connection checklist. What’s new · Developer workflows.
Get it from Microsoft Store · Browser extension · Manual Windows ZIP · Source ZIP · Checksums
- Install the companion from Microsoft Store on Windows 11 x64, open it from Start and choose Connect browsers.

manifest.json. - Enable your chosen site in ToolBraid, use Check connection in the companion and connect your AI.
Free · Store companion 0.3.3.0 · Manual companion and extension 0.4.0. The Store installs the Windows companion, not the browser extension, and follows a separate approval schedule. Use the matching 0.4.0 manual package for the complete update; do not install it over the Store edition. The manual ZIP launcher is unsigned; release status does not confer a signing certificate. See installation, edition differences and Code signing policy.

Full capabilities and requirements → · How the components connect →
- Existing Codex session or another MCP client: keep chatting and choosing models in that client.
- Optional panel chat: sign in to Codex with your ChatGPT account. Your Codex allowance applies; no API key for this route.
- Local models: use a tool-capable model in an external MCP host. The panel is not a universal provider or local-model selector.
Ask an assistant with tools on your Windows PC to help set it up:
Install and configure ToolBraid Companion using https://toolbraid.pages.dev/agent-setup.txt. Check my existing installation, verify the official download's SHA-256, preserve other MCP settings, and finish with a read-only connection test.
Copy the complete setup prompt · Manual setup. Browser permissions and account sign-in may still need you.
