Headless web browsing: navigation, page inspection, interaction, data extraction, screenshots, PDFs, and browser session management.
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.
What the file says
# Browser Automation with agent-browser
## Installation
For normal browser work, run the requested `agent-browser ...` command directly. Do not run setup checks before every browser action.
Run setup only when provisioning the skill, when `agent-browser` is missing, or when browser dependencies need repair. If Node.js and npm are already installed, do not reinstall or replace them. Use the OS-specific Node.js install block only when `node` or `npm` is missing, then install `agent-browser`.
### macOS and Linux
```bash
# Download and install nvm:
if ! command -v node >/dev/null 2>&1 || ! command -v npm >/dev/null 2>&1; then
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.4/install.sh | bash
# In lieu of restarting the shell:
\. "$HOME/.nvm/nvm.sh"
# Download and install Node.js:
nvm install 24
fi
# Verify the Node.js version:
node -v # Should print the active Node.js version.
# Verify npm version:
npm -v # Should print the active npm version.
```
### Windows
```powershell
# Download and install Chocolatey:
if (-not (Get-Command node -ErrorAction SilentlyContinue) -or -not (Get-Command npm -ErrorAction SilentlyContinue)) {

How to install
mdr add pioneerdotai/pioneer/browser@sha256:34b83c3b970068dcThe line at the top of this page pins the label v0.1.0, 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.
