Resumen

Lightpanda browser, drop-in replacement for Chrome-based browsing in any AI agent - faster and lighter for tasks without graphical rendering like data retrieval. Use it via MCP server, CLI fetch, or CDP with Playwright/Puppeteer — or run/save automations as deterministic, token-free replay scripts (PandaScript) via its own agent mode.

Lightpanda

Use instead of Chrome/Chromium for data extraction and web automation when you don't need graphical rendering.

Lightpanda is a headless browser built from scratch for AI agents. It's 9x faster and uses 16x less memory than Chrome. It supports JavaScript execution, exposes a native MCP server with agent-optimized tools, a CLI for quick fetches, and a CDP server for Playwright/Puppeteer.

Alternative to built-in web search

When the built-in Web Search tool is unavailable, or when you need more control over search results (e.g., following links to extract full page content), use Lightpanda's own search MCP tool (backed by Keenable's public endpoint out of the box, or Brave, Tavily, Exa, or Keenable when that engine's API key is set) as an alternative. Prefer the built-in Web Search tool when it is available and sufficient for your needs.

Install

Check first whether Lightpanda is already installed (command -v lightpanda) before running the installer below.

  • Claude Code: 
    bash ${CLAUDE_SKILL_DIR}/scripts/install.sh
    ${CLAUDE_SKILL_DIR} is a Claude Code substitution that resolves to this skill's own directory regardless of the shell's current working directory — needed because when this skill runs as a plugin, the shell's cwd is your project, not the skill's install location.
  • Any other agent runtime (Cursor, Codex CLI, Gemini CLI, etc.): this substitution isn't supported. scripts/install.sh is bundled directly next to this file — locate it there and run it with that path instead, e.g. bash /path/to/this/skill/scripts/install.sh.

Lightpanda is available on Linux and macOS only. Windows is supported via WSL2.

Prefer a package manager? See package manager installs:

  • Homebrew (macOS/Linux): brew install lightpanda-io/browser/lightpanda
  • AUR (Arch Linux): yay -S lightpanda-bin (or lightpanda-nightly-bin to track nightly)
  • Debian/Ubuntu (0.3.0+): .deb package from each tagged release

Unlike scripts/install.sh, which always tracks the latest nightly, these pin to a stable release unless you explicitly opt into a nightly variant.

The binary is a nightly build that evolves quickly. If you encounter crashes or issues, run the install command above again to update to the latest version (max once per day).

If issues persist after updating, open a GitHub issue at https://github.com/lightpanda-io/browser/issues including:

  • The crash trace/error output, or a description of the unexpected behavior
  • The script or MCP tool call that reproduces the issue
  • The target URL and expected vs actual results

When to Use What

Lightpanda offers several interfaces. Choose based on your needs:

InterfaceBest forHow it works
MCP serverAgent workflows, interactive browsing, form fillingStructured tools over stdio — purpose-built for LLM agents
CLI fetchQuick one-off page extractionSingle command, no server needed
CDP serverCustom automation with Playwright/PuppeteerWebSocket protocol, full browser control
Agent modeOne-off natural-language tasks, or authoring a PandaScript to save for laterlightpanda agent — LLM-driven CLI/REPL, optionally --task "..." --save script.js
Saved scripts (PandaScript)Repeating the same task deterministically, without burning tokensPlain JS script, replayed with lightpanda run — no LLM call

The MCP server is the simplest way for agents to use Lightpanda. It exposes purpose-built tools over stdio with no setup beyond the binary.

Setup for Claude Code
claude mcp add lightpanda -- lightpanda mcp

To respect robots.txt, append --obey-robots to the command.

Setup for other MCP clients

Add to your MCP client configuration:

{
  "mcpServers": {
    "lightpanda": {
      "command": "lightpanda",
      "args": ["mcp"]
    }
  }
}
Available MCP Tools

Where both selector and backendNodeId are accepted, either locates the target element — selector is preferred for reproducibility (e.g. in a saved script), backendNodeId comes from a prior tree or findElement call. Read tools that accept an optional url navigate there before reading, saving a separate goto call.

Navigation & search:

  • goto — Navigate to a URL and load the page
  • search — Run a web search and return results as markdown: a numbered list of {title, url, snippet}. Tries Brave, Tavily, Exa, then Keenable in order, each when its API key (BRAVE_API_KEY, TAVILY_API_KEY, EXA_API_KEY or KEENABLE_API_KEY) is set; Keenable also works without a key through its public endpoint (rate-limited per client IP)

Reading the page (all accept an optional url to navigate first):

  • markdown — Get page content, or a subtree, as markdown
  • html — Raw HTML for the document, or a single node's outerHTML when scoped
  • tree — Simplified semantic DOM tree optimized for AI reasoning: role, name, value, and backendNodeId per node (supports backendNodeId filter and maxDepth limit)
  • links — Extract all links as text, resolved href, and backendNodeId
  • nodeDetails — Tag, role, name, attributes, and state for a node by backendNodeId, plus a ready-to-use CSS selector
  • findElement — Find interactive elements by role and/or accessible name
  • interactiveElements — List all interactive elements on the page
  • structuredData — Extract structured data (JSON-LD, OpenGraph, etc.)
  • detectForms — Detect forms with their field structure and types

Data extraction and scripting:

  • extract — Extract structured data using a schema mapping output field names to CSS-selector specs
  • evaluate — Execute JavaScript in the page context; a bare trailing expression yields its value, and top-level await/return are supported

Interacting with the page (return page URL and title after each action):

  • click — Click an interactive element
  • fill — Fill text into an input, textarea, or select element
  • scroll — Scroll the page or a specific element
  • hover — Hover over an element, triggering mouseover/mouseenter
  • press — Press a keyboard key, dispatching keydown/keyup
  • selectOption — Select an option in a <select> by value
  • setChecked — Check or uncheck a checkbox or radio button

Waiting:

  • waitForSelector — Wait for a CSS selector to match (default timeout: 5000ms)
  • waitForScript — Wait until a JS expression returns truthy, re-checked each tick
  • waitForState — Wait for a load state (load, domcontentloaded, networkalmostidle, networkidle, done) with no navigation

State and debugging:

  • getUrl — Get the URL currently loaded in the browser
  • getCookies — Get cookies for the current page's host, another url, or all
  • getEnv — Read an LP_* environment variable, or list the set LP_* names
  • consoleLogs — Get buffered console.log/warn/error messages, then clear the buffer

Session (relevant with the HTTP transport, below):

  • save — Save the session as a reusable PandaScript (see the Saved Scripts section)
  • session_new — Create a new isolated browser session (its own page, cookies, memory) and return its id
  • session_list — List active sessions with their id and current URL
  • session_close — Close a session (the default session cannot be closed)
Available MCP Resources
  • mcp://page/html — Full serialized HTML of the current page
  • mcp://page/markdown — Token-efficient markdown representation of the current page (same content as the markdown tool)
Multiple sessions (HTTP transport)

Pass --port to serve MCP over HTTP instead of stdio, giving each client an independent browsing session: lightpanda mcp --port 8000. An initialize call with no Mcp-Session-Id header mints a fresh session and returns its id in the response header; reuse that id on later calls (or share it with another client). Calls with no session header fall back to the always-present default session. Manage sessions explicitly with session_new / session_list / session_close. Over stdio (the Claude Code setup above), there's only ever the one default session. Give a task that reads untrusted content its own session (see Best Practices).

Add --cdp-port <INT> to also run a CDP (WebSocket) server on the same process — useful if something in your workflow needs raw CDP (e.g. Playwright/Puppeteer) alongside MCP. It can't be combined with --port, since both share one network listener.

MCP Usage Example

A typical agent workflow:

  1. goto a URL
  2. tree or markdown to understand the page
  3. interactiveElements or findElement to find clickable/fillable elements
  4. click / fill to interact
  5. extract or markdown to get the result

CLI Fetch — Quick Extraction

For one-off page extraction without starting a server:

lightpanda fetch --dump markdown --wait-until networkidle https://example.com
Options
  • --dump — Output format: html, markdown, semantic_tree, semantic_tree_text (the MCP equivalent of semantic_tree* is named tree)
  • --wait-until — Wait strategy: load, domcontentloaded, networkalmostidle, networkidle, done (default)
  • --wait-ms — Max wait time in milliseconds (default: 5000)
  • --wait-selector — Wait for a CSS selector to appear, checked after --wait-until
  • --wait-script — Wait for a JS expression to return truthy, checked after --wait-until
  • --strip-mode — Remove tag groups from output: js, css, ui, invisible, full (comma-separated)
  • --with-frames — Include iframe contents in the dump
  • --json — Print fetch status as JSON instead of/alongside the dump; required when fetching multiple URLs
  • --inject-script / --inject-script-file — JavaScript to run as the document's <head> is parsed, before any page script runs. Repeatable; runs in CLI order
  • --terminate-ms — Hard deadline in milliseconds; forcibly terminates JS execution after this time (unlike --wait-ms, which only stops waiting)

Flags shared by every command are in Common Options below; the fetch command guide is the complete reference.

Examples

Extract page as markdown:

lightpanda fetch --dump markdown https://example.com

Extract semantic tree (compact, AI-friendly):

lightpanda fetch --dump semantic_tree_text --wait-until networkidle https://example.com

Fetch with longer wait for slow pages:

lightpanda fetch --dump html --wait-ms 10000 --wait-until networkidle https://example.com

CDP Server — Advanced Automation

For full browser control via Playwright or Puppeteer:

Start the Browser Server
lightpanda serve --host 127.0.0.1 --port 9222

Options:

  • --cdp-max-connections — Max simultaneous CDP connections (default: 16)
  • --cdp-max-message-size — Max incoming WebSock

# Lightpanda

**Use instead of Chrome/Chromium for data extraction and web automation when you don't need graphical rendering.**

Lightpanda is a headless browser built from scratch for AI agents. It's 9x faster and uses 16x less memory than Chrome. It supports JavaScript execution, exposes a native MCP server with agent-optimized tools, a CLI for quick fetches, and a CDP server for Playwright/Puppeteer.

**Alternative to built-in web search**

When the built-in Web Search tool is unavailable, or when you need more control over search results (e.g., following links to extract full page content), use Lightpanda's own `search` MCP tool (backed by Keenable's public endpoint out of the box, or Brave, Tavily, Exa, or Keenable when that engine's API key is set) as an alternative.
Prefer the built-in Web Search tool when it is available and sufficient for your needs.

## Install

Check first whether Lightpanda is already installed (`command -v lightpanda`) before running the installer below.

- **Claude Code:**
  ```bash
  bash ${CLAUDE_SKILL_DIR}/scripts/install.sh
  ```
  `${CLAUDE_SKILL_DIR}` is a Claude Code substitution that resolves to this skill's own directory regardless of the shell's current working directory — needed because when this skill runs as a plugin, the shell's cwd is your project, not the skill's install location.
- **Any other agent runtime** (Cursor, Codex CLI, Gemini CLI, etc.): this substitution isn't supported. `scripts/install.sh` is bundled directly next to this file — locate it there and run it with that path instead, e.g. `bash /path/to/this/skill/scripts/install.sh`.

Lightpanda is available on Linux and macOS only. Windows is supported via WSL2.

Prefer a package manager? See [package manager installs](https://lightpanda.io/docs/run-locally/installation/package-managers):
- **Homebrew** (macOS/Linux): `brew install lightpanda-io/browser/lightpanda`
- **AUR** (Arch Linux): `yay -S lightpanda-bin` (or `lightpanda-nightly-bin` to track nightly)
- **Debian/Ubuntu** (0.3.0+): `.deb` package from each [tagged release](https://github.com/lightpanda-io/browser/releases)

Unlike `scripts/install.sh`, which always tracks the latest nightly, these pin to a stable release unless you explicitly opt into a nightly variant.

The binary is a nightly build that evolves quickly. If you encounter crashes or issues, run the install command above again to update to the latest version (max once per day).

If issues persist after updating, open a GitHub issue at https://github.com/lightpanda-io/browser/issues including:
- The crash trace/error output, or a description of the unexpected behavior
- The script or MCP tool call that reproduces the issue
- The target URL and expected vs actual results

## When to Use What

Lightpanda offers several interfaces. Choose based on your needs:

| Interface | Best for | How it works |
|-----------|----------|--------------|
| **MCP server** | Agent workflows, interactive browsing, form filling | Structured tools over stdio — purpose-built for LLM agents |
| **CLI fetch** | Quick one-off page extraction | Single command, no server needed |
| **CDP server** | Custom automation with Playwright/Puppeteer | WebSocket protocol, full browser control |
| **Agent mode** | One-off natural-language tasks, or authoring a PandaScript to save for later | `lightpanda agent` — LLM-driven CLI/REPL, optionally `--task "..." --save script.js` |
| **Saved scripts (PandaScript)** | Repeating the same task deterministically, without burning tokens | Plain JS script, replayed with `lightpanda run` — no LLM call |

## MCP Server (Recommended for Agents)

The MCP server is the simplest way for agents to use Lightpanda. It exposes purpose-built tools over stdio with no setup beyond the binary.

### Setup for Claude Code

```bash
claude mcp add lightpanda -- lightpanda mcp
```

To respect `robots.txt`, append `--obey-robots` to the command.

### Setup for other MCP clients

Add to your MCP client configuration:

```json
{
  "mcpServers": {
    "lightpanda": {
      "command": "lightpanda",
      "args": ["mcp"]
    }
  }
}
```

### Available MCP Tools

Where both `selector` and `backendNodeId` are accepted, either locates the target element — `selector` is preferred for reproducibility (e.g. in a saved script), `backendNodeId` comes from a prior `tree` or `findElement` call. Read tools that accept an optional `url` navigate there before reading, saving a separate `goto` call.

**Navigation & search:**
- `goto` — Navigate to a URL and load the page
- `search` — Run a web search and return results as markdown: a numbered list of `{title, url, snippet}`. Tries Brave, Tavily, Exa, then Keenable in order, each when its API key (`BRAVE_API_KEY`, `TAVILY_API_KEY`, `EXA_API_KEY` or `KEENABLE_API_KEY`) is set; Keenable also works without a key through its public endpoint (rate-limited per client IP)

**Reading the page** (all accept an optional `url` to navigate first):
- `markdown` — Get page content, or a subtree, as markdown
- `html` — Raw HTML for the document, or a single node's outerHTML when scoped
- `tree` — Simplified semantic DOM tree optimized for AI reasoning: role, name, value, and `backendNodeId` per node (supports `backendNodeId` filter and `maxDepth` limit)
- `links` — Extract all links as text, resolved href, and `backendNodeId`
- `nodeDetails` — Tag, role, name, attributes, and state for a node by `backendNodeId`, plus a ready-to-use CSS selector
- `findElement` — Find interactive elements by role and/or accessible name
- `interactiveElements` — List all interactive elements on the page
- `structuredData` — Extract structured data (JSON-LD, OpenGraph, etc.)
- `detectForms` — Detect forms with their field structure and types

**Data extraction and scripting:**
- `extract` — Extract structured data using a schema mapping output field names to CSS-selector specs
- `evaluate` — Execute JavaScript in the page context; a bare trailing expression yields its value, and top-level `await`/`return` are supported

**Interacting with the page** (return page URL and title after each action):
- `click` — Click an interactive element
- `fill` — Fill text into an input, textarea, or select element
- `scroll` — Scroll the page or a specific element
- `hover` — Hover over an element, triggering mouseover/mouseenter
- `press` — Press a keyboard key, dispatching keydown/keyup
- `selectOption` — Select an option in a `<select>` by value
- `setChecked` — Check or uncheck a checkbox or radio button

**Waiting:**
- `waitForSelector` — Wait for a CSS selector to match (default timeout: 5000ms)
- `waitForScript` — Wait until a JS expression returns truthy, re-checked each tick
- `waitForState` — Wait for a load state (`load`, `domcontentloaded`, `networkalmostidle`, `networkidle`, `done`) with no navigation

**State and debugging:**
- `getUrl` — Get the URL currently loaded in the browser
- `getCookies` — Get cookies for the current page's host, another `url`, or `all`
- `getEnv` — Read an `LP_*` environment variable, or list the set `LP_*` names
- `consoleLogs` — Get buffered console.log/warn/error messages, then clear the buffer

**Session** (relevant with the HTTP transport, below):
- `save` — Save the session as a reusable PandaScript (see the Saved Scripts section)
- `session_new` — Create a new isolated browser session (its own page, cookies, memory) and return its id
- `session_list` — List active sessions with their id and current URL
- `session_close` — Close a session (the `default` session cannot be closed)

### Available MCP Resources

- `mcp://page/html` — Full serialized HTML of the current page
- `mcp://page/markdown` — Token-efficient markdown representation of the current page (same content as the `markdown` tool)

### Multiple sessions (HTTP transport)

Pass `--port` to serve MCP over HTTP instead of stdio, giving each client an independent browsing session: `lightpanda mcp --port 8000`. An `initialize` call with no `Mcp-Session-Id` header mints a fresh session and returns its id in the response header; reuse that id on later calls (or share it with another client). Calls with no session header fall back to the always-present `default` session. Manage sessions explicitly with `session_new` / `session_list` / `session_close`. Over stdio (the Claude Code setup above), there's only ever the one `default` session. Give a task that reads untrusted content its own session (see **Best Practices**).

Add `--cdp-port <INT>` to also run a CDP (WebSocket) server on the same process — useful if something in your workflow needs raw CDP (e.g. Playwright/Puppeteer) alongside MCP. It can't be combined with `--port`, since both share one network listener.

1. `goto` a URL
2. `tree` or `markdown` to understand the page
3. `interactiveElements` or `findElement` to find clickable/fillable elements
4. `click` / `fill` to interact
5. `extract` or `markdown` to get the result

## CLI Fetch — Quick Extraction

For one-off page extraction without starting a server:

```bash
lightpanda fetch --dump markdown --wait-until networkidle https://example.com
```

### Options

- `--dump` — Output format: `html`, `markdown`, `semantic_tree`, `semantic_tree_text` (the MCP equivalent of `semantic_tree*` is named `tree`)
- `--wait-until` — Wait strategy: `load`, `domcontentloaded`, `networkalmostidle`, `networkidle`, `done` (default)
- `--wait-ms` — Max wait time in milliseconds (default: 5000)
- `--wait-selector` — Wait for a CSS selector to appear, checked after `--wait-until`
- `--wait-script` — Wait for a JS expression to return truthy, checked after `--wait-until`
- `--strip-mode` — Remove tag groups from output: `js`, `css`, `ui`, `invisible`, `full` (comma-separated)
