README

can-see

MCP server that lets AI agents see and interact with terminal/CLI applications through virtual terminals and PNG screenshots.

Built for Claude Code and any MCP-compatible agent.

Why?

Some things are easier to show than describe. When debugging a TUI app, an interactive CLI wizard, or anything with visual terminal output, can-see lets the agent see exactly what you see — colors, layout, cursor position, and all.

How it works

Launch a CLI app in a virtual terminal (node-pty + @xterm/headless)
Screenshot the terminal as a PNG image (rendered via node-canvas)
Send keys/text to interact with the app
Screenshot again to see the result
Close the session when done

Installation

npm install -g can-see

Prerequisites

can-see depends on node-canvas (Cairo) and node-pty, which require native compilation. Most systems will need:

Windows: Visual Studio Build Tools (C++ workload) — npm install --global windows-build-tools or install from Visual Studio Installer
macOS: Xcode Command Line Tools — xcode-select --install
Linux: sudo apt install build-essential libcairo2-dev libjpeg-dev libpango1.0-dev libgif-dev librsvg2-dev

Configuration

Claude Code

Add to your project's .mcp.json:

{
  "mcpServers": {
    "can-see": {
      "command": "npx",
      "args": ["-y", "can-see"]
    }
  }
}

Or if installed globally:

{
  "mcpServers": {
    "can-see": {
      "command": "can-see"
    }
  }
}

Other MCP clients

can-see uses stdio transport. Point your MCP client at the can-see binary or npx -y can-see.

Tools

Tool	Description
`launch`	Start a CLI app in a virtual terminal. Returns a `sessionId`.
`screenshot`	Capture the terminal as a PNG image.
`screenshot_region`	Capture a specific rectangular area of the terminal.
`capture_baseline`	Snapshot terminal state for later diff comparison.
`diff_screenshot`	Compare current state against baseline with highlighted changes.
`get_cell_info`	Query character, colors, and attributes at specific cell(s).
`read_text`	Read the terminal buffer as plain text.
`read_scrollback`	Read text that scrolled above the visible viewport.
`wait_for_text`	Wait until specific text appears in the terminal buffer.
`wait_for_idle`	Wait until terminal output has been stable for a given duration.
`wait_for_color`	Wait until a specific color appears at a position.
`start_recording`	Begin capturing frames for an animated GIF.
`stop_recording`	Stop recording and return the animated GIF.
`send_keys`	Send keystrokes (e.g., `Enter`, `Ctrl+C`, `['Down', 'Down', 'Enter']`).
`send_text`	Type a string of text into the app.
`list_sessions`	List all active terminal sessions.
`close`	Kill the app and clean up. Always close when done.

Supported keys

Enter, Tab, Escape, Backspace, Space, Up, Down, Left, Right, Home, End, Delete, PageUp, PageDown, Ctrl+A through Ctrl+Z.

Environment variables

Variable	Default	Description
`DEFAULT_COLS`	`120`	Terminal width in columns
`DEFAULT_ROWS`	`30`	Terminal height in rows
`IDLE_TIMEOUT_MS`	`300000`	Auto-close idle sessions after this many ms (5 min)

Example usage

From an MCP-connected agent:

Agent: I'll launch your app to see what's happening.
→ launch("node", ["app.js"])  → sessionId: "abc-123"

Agent: Let me wait for the app to start.
→ wait_for_text("abc-123", "Ready")  → Found "Ready" after 1200ms

Agent: Let me read the current output.
→ read_text("abc-123
