"Socket" matching MCP servers:

Lets any number of concurrent Claude Code sessions drive a Firefox browser through the Browser Control extension by funneling every session's commands over a single shared port via a background daemon and private unix socket. Sessions no longer have to compete for a limited pool of extension ports, and requests stay isolated through per-request correlation ids.

Enables coding agents to drive a persistent local Chromium — navigating, clicking, filling, uploading, downloading, screenshotting, and reading the accessibility tree — with caller-chosen request IDs that yield honest, never-replayed action outcomes. It also exposes Phoenix runtime tools such as docs, source locations, logs, evaluation, and SQL over a private Unix socket, without requiring an open browser.

A local MCP server for Firefox that gives AI agents full control over the browser via a Unix socket, enabling automation of tabs, pages, cookies, and more without exposing any network ports.

Enables Claude Code to drive a local Firefox browser: opening and managing tabs, navigating, reading page structure and text, clicking, typing, filling forms, running JavaScript, taking screenshots, and inspecting console messages and network requests. Everything runs over a local Unix socket with no network traffic, and actions are restricted to tabs explicitly placed under Claude's control.

Playwright browser MCP for coding agents working behind a full-tunnel VPN. The tunnel stays up so the agent keeps reaching its API, while the browser's own traffic egresses through your real ISP — for services that reject the tunnel's exit IP: domestic APIs, payment and SMS gateways, bank endpoints. Per-socket binding plus a LAN-bound proxy, with per-host routing rules so you choose which hosts go
