Konnect
This server does not currently have a deployable release on Glama. Follow the repository's setup instructions to install and configure it for your MCP client, including any required credentials and local dependencies.
Konnect
A local browser-automation bridge that lets AI agents drive your real browser — your actual login sessions, cookies, and tabs — instead of a cloud sandbox or headless instance. Konnect connects MCP-compatible coding agents (and a token-cheap CLI) to Comet Browser via a long-lived daemon and a Chrome MV3 extension.
Status: production. Runs on macOS via launchd (port 9223).
Architecture
A persistent aiohttp daemon (daemon/, listens on :9223) owns the WebSocket to
a Chrome MV3 extension (extension/) that performs the actual page interaction;
the WS survives MV3 service-worker eviction via an offscreen document. Two thin
clients front the daemon's HTTP API: an MCP stdio shim (mcp/) for AI agents and
a CLI (cli/) for low-token coding. The daemon is the single source of truth —
MCP is one client, not the only interface.
See ARCHITECTURE.md for full design rationale and the
decision tree (why daemon-over-MCP, why snapshot-first, why CLI+SKILL alongside MCP).

# 1. Python deps (aiohttp for the daemon)

# 2. Install + start the daemon under launchd
deploy/install.sh
# 3. Load the extension (one-time, manual)
# chrome://extensions (or comet://extensions) → Developer mode → Load unpacked
# → choose this repo's extension/ directorydeploy/install.sh auto-detects a Python with aiohttp (or takes an explicit
path: deploy/install.sh /path/to/python). It renders local.konnect.daemon.plist
with your $HOME and repo path — no hardcoded user paths.
Verify the daemon sees the extension:
curl http://127.0.0.1:9223/health # → {"extension_connected": true}Logs: /tmp/konnect-daemon.log. Stop: launchctl unload ~/Library/LaunchAgents/local.konnect.daemon.plist.
Usage — MCP tools
Wire mcp/konnect_mcp.py as an MCP server in your agent (Claude, Cursor, opencode).
Exposed tools (all proxy to the daemon over HTTP):
Tool | Purpose |
| Check daemon + extension connection |
| List open browser tabs (group + blocked state) |
| Select an already-open tab by URL prefix |
| Open a URL (new background tab by default) |
| AX-style accessibility tree with |
| Click an element by ref |
| Fill an input/textarea/select/contenteditable by ref |
| Capture tab/element to a PNG file (read via |
| Visible text of the current tab |
| Run JS in the page main world (fallback for ref limits) |
Targeting is snapshot-first: call konnect_snapshot, read the ref=N tags, then
konnect_click/konnect_fill by ref. Screenshots write to disk and are read with
Read — never base64 into context.
Security
Bearer-token auth (
extension/token.json), generated by the daemon; tokens are git-ignored and never committed.evaluateruns in the MAIN world for trusted local use only. Sites that checkevent.isTrustedmay reject synthetic events — a product boundary, not a bug.
