Read this skill before the first step that uses the built-in browser, the browser pane inside the Claude desktop app (also called the in-app browser, the browser pane, Claude's browser, or "your own browser"), whose tools are named mcp__Claude_Browser__* when the session runs in the desktop app and mcp__remote-devices__Claude_Browser__* when a cloud session is linked to the person's computer; before those tools are turned on there may be a single enable__mcp__remote-devices__Claude_Browser…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Built-in browser The built-in browser is a real browser pane inside the Claude desktop app, separate from the person's Chrome. Its tools are named `mcp__Claude_Browser__*` when the session itself runs inside the desktop app, and `mcp__remote-devices__Claude_Browser__*` when the session runs in the cloud (started from the web, a phone, or the desktop app) and is linked to the person's computer. The names after the prefix are the same either way, Claude uses whichever prefix is actually present, and this skill refers to the tools by the part after the prefix.

How to install
mdr add razshy/wiggle/built-in-browser@sha256:d665ad235c04894aThe line at the top of this page pins the label git:20260904.bb60abf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
