Every run gets a Pullfrog MCP server with tools for pull requests, reviews, issues, CI logs and git. The tools enforce the repository’s push and shell settings, and some appear only when the run needs them.

Browser

The agent can drive a headless Chrome browser with agent-browser. It starts your app, opens it and checks its own work the way a reviewer would.
  • Open pages, including a dev server the agent starts in the background with the shell tool.
  • Click, type and fill in forms.
  • Read the page structure and the console output to debug a UI.
  • Take screenshots and post them in a comment or PR with upload_file.
The browser runs through the shell, so a run with the shell disabled has no browser. Pullfrog installs it the first time the agent uses it, so runs that never open a page skip the install.
