A new server you create. It is not this listing's official endpoint. Use the publisher install when you want their URL and their credentials.
실행Claude Code's WebFetch gets 403'd on most sites. Ask it to pull up a doc, check a Reddit thread, or look at a GitHub issue, and it comes back with a 403 — because server-side fetchers don't have your cookies, your logins, or your sessions.
Browser Buddy is a small local MCP bridge: a Chrome extension (Manifest V3) talks to a Python native-messaging host, which exposes two MCP tools. Your agent reads pages exactly as you see them — logged in, past bot checks — and the page never leaves your machine except into the agent's context.
Stdlib only. No dependencies, no cloud, no API keys.

This writes com.browserbuddy.host.json into Chrome's NativeMessagingHosts
directory (Linux/macOS) pointing at browser_buddy_host.py. Restart Chrome,
then open the extension's service worker console — you should see
[browser-buddy] native host connected.
claude mcp add browser-buddy -- python3 /absolute/path/to/pypi/browser_buddy_mcp.py
Or in ~/.claude.json / project .mcp.json:
{
"mcpServers": {
"browser-buddy": {
"command": "python3",
"args": ["/absolute/path/to/browser-buddy/pypi/browser_buddy_mcp.py"]
}
}
}
Requires Python 3.9+. No pip install needed — or install the published
package: pip install browser-buddy-mcp (built from pypi/; the browser-buddy-mcp
command is the entry point).
Vendor scrapers (Firecrawl, etc.) fetch pages server-side: they never have your cookies, can't get past SSO/2FA/login walls, can't see what you see behind an account, and they charge per page. The official Claude in Chrome goes the other way — full autonomous browser control — but ships a permission dialog per tool call (dozens per session) and sits at 2.7 stars on the Chrome Web Store.
Browser Buddy picks the middle: read-only access through the browser you already logged into. No credentials leave your machine, nothing to pay per page, no dialog spam — just "let the agent see what I see."
(truncated)).open_and_read_url opens URLs in your real, logged-in browser. A
prompt-injected page could otherwise steer the agent toward your email or
other sensitive sites. Restrict which domains the agent may open:
// ~/.config/browser-buddy/config.json
{
"allowed_domains": ["github.com", "stackoverflow.com"]
}
Entries match the domain and its subdomains (docs.github.com is covered by
github.com). When the list is empty (default), any URL is allowed but the
server logs a warning recommending you set it. URLs outside the list are
refused before anything is opened. read_active_tab is unaffected — it only
reads the tab you already opened.
