ThinkRun — Screen Recorder for AI Coding Agents

Stop screenshotting bugs and typing paragraphs to explain them. ThinkRun records any browser session — or lets your agent record what it built — and turns it into structured context your AI coding agent can act on: every click, the console, network requests, your voice narration, and screenshots, all time-synced. Not just a screenshot. Not just a video.

Works with Claude Code, Cursor, Cline, Windsurf, and any MCP client.

Install

npx @thinkrun/mcp

Or install the CLI globally:

npm install -g @thinkrun/cli

The CLI automatically installs the native host binary, which lets AI tools control Chrome.

Add to your MCP config

{
  "mcpServers": {
    "thinkrun": {
      "command": "npx",
      "args": ["@thinkrun/mcp"]
    }
  }
}

Config location:

• Claude Code: ~/.claude/settings.json

• Cursor: .cursor/mcp.json

• Cline: VS Code settings → Cline MCP Servers

Then ask your agent: "navigate to localhost:3000 and screenshot the checkout page" — or record the bug yourself and hand the agent the result.

Why ThinkRun

Other tools give your agent eyes. ThinkRun gives it structured sight — context it can parse in one pass instead of you re-explaining the page.

Agent skills for Claude Code, Cursor, Codex & Gemini CLI

Four portable agent skills ship in this repo, mirrored for every major harness (.claude/skills/, .cursor/skills/, .codex/skills/, .gemini/skills/):

• web-browse — browse the web programmatically: drive a real or cloud browser to navigate, interact, extract, and screenshot.

• ux-audit — walk through a product UI as a real user, screenshot every step, and produce a structured UX report with a prioritized fix list.

• thinkbrowse-cli — drive the browser from shell scripts via the thinkrun CLI.

• thinkbrowse-mcp — drive the browser through the ThinkRun MCP server's tools.

Install without cloning — the repo is served as a live MCP server that auto-updates on every commit:

{ "mcpServers": { "thinkrun-skills": { "url": "https://mcp.skillsovermcp.com/mcp/dundas/thinkrun" } } }

Trigger accuracy is measured, not claimed. Every skill ships a 20-query trigger-eval fixture, and evals/BENCHMARK.md publishes the results: 79–80/80 routing accuracy on 12 of the 16 published model configurations (GPT-5.4/5.5/5.6 and Claude Sonnet/Opus/Fable families; the outliers are a documented strict-reading mode, not crashes), plus catalog-ablation runs showing the skills absorb each other's traffic when installed as a subset. Reproduce with bun evals/run-eval.ts build.

Manual binary install

If you need to install the native host without the CLI, download the binary for your platform from the latest release and run:

chmod +x thinkbrowse-host-* && ./thinkbrowse-host-* --install

The native host binary keeps the thinkbrowse-host filename for now — it's the same signed binary, unchanged by the rename.

FAQ

How do I give Claude Code (or Cursor) access to my browser?

Add ThinkRun as an MCP server — npx @thinkrun/mcp — and your agent can drive and read a real Chrome session, your cookies and logins included. See "Add to your MCP config" above.

How do I show Cursor a UI bug instead of pasting a screenshot?

Record the bug with ThinkRun. Instead of a flat image, your agent gets a structured artifact — the steps you took, the console errors, the failing network requests, and the DOM state at the moment it broke — so it fixes the actual problem instead of guessing from a picture.

Is there an MCP server that uses my real Chrome cookies and sessions?

Yes. ThinkRun runs against your real Chrome via a native host, so authenticated pages just work — no headless re-login, no separate profile, no fighting your browser for the Chrome profile.

How do I record a browser session for an AI coding agent?

Run npx @thinkrun/mcp (or npm i -g @thinkrun/cli) and record any session — or let the agent record what it built. ThinkRun turns it into an AI-ready report (clicks, console, network, narration, screenshots, all time-synced), available as a shareable link and as LLM-ready Markdown/JSON.

How do I give my AI coding agent context about what went wrong?

Hand it a ThinkRun recording. The structured "what happened" — actions, first bad signal, expected vs actual, and the element state — is exactly the context an agent needs to land a fix on the first try.
