Same key everywhere. Works with any MCP client that supports remote HTTP and Bearer auth — Cursor and Claude Code are the ones we document first. Start with Chrome setup, then paste the JSON into your client (or use the Claude web connector).
Chrome extension
Install the extension, mint your one-time key, and confirm the relay.
Any MCP client
Replace YOUR_BCN_KEY with the key from extension setup. Paste the JSON into your client's MCP settings (Cursor, Claude Code, Windsurf, Cline, Zed, and others). Claude Code: you can use the one-liner below instead.
claude mcp add --transport http beacon https://mcp.trybeacon.space/mcp --header "Authorization: Bearer YOUR_BCN_KEY"
{
"mcpServers": {
"beacon": {
"url": "https://mcp.trybeacon.space/mcp",
"headers": {
"Authorization": "Bearer YOUR_BCN_KEY"
}
}
}
}Claude web
Remote MCP URL, Bearer header, and the same bcn key. Keep the extension linked in Chrome.
Cursor & Claude Code
Optional but recommended: copy the skill into ~/.cursor/skills/beacon-browser/ or ~/.claude/skills/beacon-browser/, then invoke /beacon-browser in chat. Install steps and FAQ are in the repo README.
