What is Bureau

Bureau is the browser stack's installable capability server. It drives a real, stealth browser (Camofox — a hardened Firefox) and exposes that browser's capabilities as MCP tools over HTTP, so an agent — Claude Code, Cursor, or any MCP client — can navigate, read, act, and capture on the live web as you.

It runs on your machine, with your logins and your sessions. Nothing is proxied through a shared cloud browser.

Architecture

Claude / agent ──MCP over HTTP :8830──▶ bureau serve ──▶ Camofox (stealth Firefox) :9377

Three pieces:

• The CLI (bureau) — installs the stack, manages saved browser identities, runs captures/searches, and starts the daemon.
• The daemon (bureau serve) — owns the browser session and serves the MCP tool catalogue at POST /mcp on port 8830 (plus GET /health and a WS /watch/:tab live screencast).
• Camofox — the stealth Firefox serve process the daemon talks to over CAMOFOX_URL (default http://127.0.0.1:9377).

What credits buy

The browser runs on your machine and is free — every control, scrape, social, screen, and session tool executes locally. Credits are spent only on the metered AI actions the daemon makes on your behalf (the llm.ask / intel.judge reasoning seam). Bring your own Anthropic key and even those are free and offline. See Pricing & credits.

Where to go next

• Install — get the CLI and Camofox onto your machine.
• Quickstart — start the daemon and connect an MCP client.
• Account & AI credits — link your account for the metered AI proxy, or stay on your own key.
• MCP tools — the full tool catalogue, by family.
