Product features
A browser workbench with controls built around the agent.
DocuBench gives MCP-compatible agents a visible desktop browser workspace, then surrounds that workspace with navigation boundaries, browser tools, site instructions, tab ownership, and reviewable activity.
Core capabilities
The control plane for browser-based agent work.
These features work together. Navigation control defines where the agent may go, browser tools define what it can do there, site instructions guide repeated work, and audit makes the session visible enough to review.
Navigation control
Set the browser workspace where an agent may operate. Known sites can open directly; unknown destinations can be blocked or sent back for approval.
Browser actions
Expose focused MCP tools for reading content, screenshots, clicking, typing, scrolling, dragging, and moving through browser history.
Audit visibility
Watch activity during the session, and keep local audit records on MCP Power User when you need a saved trail after the work is done.
Site instructions
Attach site or URL-prefix notes so repeated workflows carry the same guidance, constraints, and operating preferences for AI agents.
MCP tab model
Three tab types for three kinds of browser work.
DocuBench separates general navigation, repeated site work, and developer-hosted workflows into distinct MCP-owned browser surfaces.
General scoped work
Navigation tab
The default MCP browser surface for research, operations, and one-off tasks inside the workbench's navigation policy.
Repeated site work
Site agent tab
A dedicated tab for a known website or URL scope, with tighter boundaries and reusable instructions for recurring workflows.
Local UI workflows
Developer host tab
A controlled browser tab for localhost, staging, or another developer-owned app that an agent can inspect and operate.
Browser tool set
Practical browser actions, exposed as structured MCP tools.
The agent does not receive arbitrary browser code execution. It asks DocuBench for focused actions: inspect the current page, capture visual state, interact with controls, and return a structured result.
Content, screenshots, status, and errors come back as workbench results the user can inspect.
Audit and review
See the browser work as it happens, then inspect the trail.
Live review helps users understand current agent activity. Local audit persistence for MCP Power User keeps a saved record for people who need to examine browser actions after the session.
Live activity
Watch navigation and browser tool calls
Saved records
Keep local audit data on paid plans
