Registry nameio.github.brawsr/brawsr

How to install

What it does

Browser sessions, checkpoints, rewind, fork, lineage, and lifecycle tools for brawsr.

  • Connects Runs on your computer
  • Account or key Needs BRAWSR_API_KEY
  • Category Web & browsers

Install

Pick the AI app you use, then copy the settings.

Passed 3/3 checks · Runs on your computer · ✓ Commands checked Nov 14, 2026

First: which AI do you use?

Pick your app and the steps appear below.

Works with Claude, with some setup first

You need a brawsr key (create it on the maker’s site) · Install Node.js on your computer first (one time) · Only the Claude desktop app (Windows or Mac), not the web or phone

Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server brawsr for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "brawsr": { "command": "npx", "args": [ "-y", "@brawsr/mcp-server" ], "env": { "BRAWSR_API_KEY": "your-value" } } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) For BRAWSR_API_KEY, leave "your-value" in place and tell me to paste the real value myself into the file or the app’s field. Never ask me to type a key in chat. 5) Do what we agreed, then check that the brawsr tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

  1. Install Node.js (if you don’t have it)

    Already installed? Check first · Open Terminal, type this command and press Enter

    node -v
    • A version number such as v26.13.1 = installed, skip this step
    • "command not found" (on Windows: "is not recognized") = not installed yet, or installed but Terminal needs to be closed and reopened
    How to open Terminal

    Mac: press ⌘ + Space, type Terminal, press Enter

    Windows: open Start, type Windows PowerShell, then Open

    Not installed: Open the official download page, pick the LTS version and the click-through installer: .pkg on Mac · .msi on Windows. Double-click and follow it to the end. No curl command needed

    Open the Node.js download page ↗

    When it’s done, close Terminal, open it again and run the same command. You should see a version number: node -v

    Install once; it works for everything that needs Node.js

  2. Sign up and create a brawsr key

    Open the maker’s site, sign up and create an API key for the next step. Check the maker’s site for pricing and free plans.

    Open the brawsr site ↗

  3. Open the Claude desktop app’s settings file

    SettingsDeveloperEdit Config

  4. Paste these settings and save the file

    {
  "mcpServers": {
    "brawsr": {
      "command": "npx",
      "args": [
        "-y",
        "@brawsr/mcp-server"
      ],
      "env": {
        "BRAWSR_API_KEY": "your-value"
      }
    }
  }
}

    Paste the key only into the app’s field, never into a chat or to anyone

  5. Quit Claude and open it again

  6. Try it

    Use brawsr and tell me what you can do for me, then show me one thing

    ✓ If Claude says it is using brawsr or shows a brawsr tool in the answer, you are connected

2 optional setting(s) (works without them)

The command above works without these. Add them only if you want to change something, following the maker’s description.

  • BRAWSR_BASE_URL Optional explicit API endpoint override for local development or another deployment.
  • BRAWSR_MCP_TIMEOUT_MS Optional default lifecycle wait in milliseconds, from 1 through 300000.

Descriptions are as written by the maker.

Common questions

Is brawsr safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: BRAWSR_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 2 days ago, and the latest version (0.2.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

brawsr MCP server

The authenticated local MCP bridge for brawsr browser sessions, checkpoints, rewind, and fork. It uses the official packaged @brawsr/sdk; it does not duplicate API models, poll orchestration, or browser/CDP behavior.

The v0.2 transport is local stdio and requires Node.js 22+.

Install and configure

MCP clients spawn the server locally. Pin the package version in client configuration so an MCP client restart cannot silently select a newer release:

{

"mcpServers": { "brawsr": { "command": "npx", "args": ["-y", "@brawsr/mcp-server@0.2.0"], "env": { "BRAWSR_API_KEY": "your-brawsr-api-key" } } } }

The npm package includes the official @brawsr/sdk; no second package install is required. BRAWSR_API_KEY is the only required environment variable. The production endpoint https://api.brawsr.io is built in.

For local development or another deployment, BRAWSR_BASE_URL may explicitly override that endpoint. BRAWSR_MCP_TIMEOUT_MS optionally changes the default bounded operation wait from 30 seconds and accepts an integer from 1 through 300000.

The API key is never a tool argument or result. Standard output is reserved for MCP protocol messages. Redacted lifecycle diagnostics use standard error. A direct shell launch uses the same executable:

BRAWSR_API_KEY=... npx -y @brawsr/mcp-server@0.2.0

Tools

  • brawsr_create_session, brawsr_list_sessions, brawsr_get_session, brawsr_update_session_label, brawsr_close_session
  • brawsr_close_sessions
  • brawsr_create_checkpoint, brawsr_get_checkpoint, brawsr_list_checkpoints, brawsr_delete_checkpoint
  • brawsr_list_rewindable_checkpoints, brawsr_list_session_activity, brawsr_get_session_lineage
  • brawsr_rewind, brawsr_fork
  • brawsr_get_operation, brawsr_wait_operation

Session creation accepts an optional display_label. The same label can be changed or cleared with one brawsr_update_session_label call. Session lists are newest-first, bounded, and may include retained closed or expired sessions. brawsr_get_session includes a CDP URL only while the session is attachable.

brawsr_list_checkpoints is capture history: it can include deleted captures for audit and dashboard views. Use brawsr_list_rewindable_checkpoints when choosing a valid rewind or fork target. Lineage returns one session, its optional parent fork edge, and one bounded page of direct children; callers can follow child session IDs to browse a nested fork tree. Pagination cursors are opaque and may be passed back unchanged.

Checkpoint, rewind, and fork are one high-level tool call. The packaged SDK hides ordinary 202 polling. Rewind returns as soon as its result is CDP-usable; the operation may finish bounded post-restore work in the background. A timeout stops only local waiting and returns the operation/idempotency recovery fields; server work continues.

Fork children are independent peer sessions, not implicit winners or losers. There is no browser-state merge and no automatic sibling cleanup. Rewind restores browser/client state, not remote website side effects, and makes old CDP/browser handles stale. Long-lived WSS/SSE/WebRTC streams may need application-level reconnection.

CDP URLs are sensitive structured outputs. The MCP server never returns the Authorization header. Use the ordinary SDK or a supported framework to attach; the MCP server does not proxy CDP.

Remote Streamable HTTP, OAuth, hosted multi-tenancy, legacy HTTP+SSE, and resumable MCP sessions are deferred beyond the local v0.2 stdio boundary.

Development

npm ci

npm run verify

Release archives are built reproducibly with the pinned Node 24 and npm 11.5.1 toolchain. CI also exercises the server and its real MCP client boundary on Node 22 and Node 24. npm hosts the executable package; the official MCP Registry hosts discovery metadata for io.github.brawsr/brawsr.
