Installation

Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

Remote (streamable-http)
Claude Code 
claude mcp add --transport http unbrowse 'https://unbrowse.ai/mcp'
Configuration JSON (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "unbrowse": {
            "type": "http",
            "url": "https://unbrowse.ai/mcp"
        }
    }

NPM package unbrowse
Claude Code 
claude mcp add unbrowse -e 'UNBROWSE_API_KEY=<your unbrowse_api_key>' -- npx -y unbrowse@12.5.0 mcp

Unbrowse

Every website, even those without an official API or MCP, still rely on a first party API to talk to their backend. Unbrowse calls these website's first party APIs to make agentic browsing 50-100x faster and 95% cheaper than using a browser.

This is the open-source client for the hosted Unbrowse service (https://unbrowse.ai): the @unbrowse/sdk TypeScript client for its REST API, and the unbrowse CLI built on it.

Install the agent skill:

npx skills add unbrowse-ai/unbrowse --skill unbrowse

Connect your agent:

claude mcp add --transport http unbrowse https://unbrowse.ai/mcp

Complete OAuth sign-in in your client. From a terminal: npx unbrowse login (OAuth in your browser, nothing to paste), then npx unbrowse run 'top stories on hacker news'.

How it works

  1. Discover. Unbrowse searches your private capabilities, then a public registry of sites already compiled into tools.
  2. Run. A matching capability replays the site's own first-party HTTP requests. No browser. A run succeeds only when its result is verified.
  3. Learn once. No match: an agent does the task in Unbrowse's recorded cloud browser (MCP), or you upload two HAR recordings (unbrowse learn). Unbrowse compiles the requests into a one-call capability. Next time is step 2.

Passwords stay in the Unbrowse password manager; the CLI never takes one.

Commands

unbrowse login [--key ub_live_…]    sign in (browser OAuth) or store an API key
unbrowse discover <query>           your capabilities, then the public registry
unbrowse run <task…> [--set k=v]    run a task from your IP (--from-unbrowse: from Unbrowse); waits for a verified result
unbrowse resume <runId> k=v…        answer what the run asked for, on the same run
unbrowse scrape <url>               read one page as markdown
unbrowse index <url>                teach Unbrowse a site: each flow becomes a tool
unbrowse learn a.har b.har          compile two recordings into a capability
unbrowse logins                     saved logins, masked
unbrowse registry [query]           public compiled sites (no account)

All commands: docs/cli.md. Exit codes: 0 ok, 1 error, 2 input required, 3 sign-in or login needed, 4 not verified.

SDK

import { Unbrowse } from "@unbrowse/sdk";
const ub = new Unbrowse(); // UNBROWSE_API_KEY
const run = await ub.wait((await ub.run({ task: "top stories on Hacker News", idempotencyKey: crypto.randomUUID() })).runId);

Supported REST methods: docs/sdk.md.

Agents

Agents connect to the hosted MCP (https://unbrowse.ai/mcp, see docs/install.md) and follow skill/SKILL.md. The CLI is the REST alternative. unbrowse mcp runs a local stdio proxy to the hosted MCP for hosts that need stdio or plain tool names (unbrowse_scrape).

Plugins for Claude Code, Codex, Grok Build, OpenClaw, Hermes and elizaOS bundle the skill and make Unbrowse the host's browser: plugins/. Grok, ChatGPT, Claude, Perplexity, Le Chat and Gemini CLI connect as a custom connector: docs/connect.md.

Faut-il une clé API pour Unbrowse ?

Oui. Il attend UNBROWSE_API_KEY, à renseigner dans sa configuration.

Unbrowse est-il open source ?

Oui. Son code est sur GitHub sous licence MIT.

Qui maintient Unbrowse ?

Il est publié par unbrowse-ai. AI.tn le référence sans le maintenir ni le recommander.

Issu du registre MCP officiel. Être listé n'est pas une recommandation : vérifiez le code et les permissions d'un serveur avant de lui donner accès à vos données.
