"How to add MCP to the Firefox browser" matching MCP servers:

Security-focused Firefox browser MCP server for penetration testing, built on Playwright, enabling vulnerability scanning, session manipulation, network inspection, and reconnaissance.

Enables Codex to manage a local Firefox session by listing, grouping, opening, activating, navigating, and closing non-private tabs and native tab groups through a secure local native-messaging bridge.

Enables Claude Code to inspect network traffic, query the DOM, read console logs, and capture WebSocket frames in Firefox.

Enables users to discover jobs by target titles and countries, rank job descriptions by skill coverage across all imported resumes, generate tailored ATS-ready resumes and cover letters, and fill and submit requested application batches through a signed-in AI host with browser access.

Enables users to record, review, verify, and expose permitted browser workflows as callable MCP tools with typed inputs, isolated Chromium verification, and approval-gated writes.

Enables converting webpages into structured JSON using CSS-selector schemas, with anti-bot handling and support for protected pages.

Enables converting any webpage to clean LLM-ready markdown, with extraction, article, and news modes, using a real browser with anti-bot handling.

Fetches a URL and returns the main content as clean Markdown, using plain HTTP when possible and headless Chromium for JavaScript-rendered or bot-protected pages.

MCP server that converts web page URLs to Markdown via the Zyla API.

Enables AI agents to fetch one or many web pages concurrently and receive clean, LLM-ready Markdown with navigation, ads and boilerplate stripped away, plus extracted metadata such as title, description, author, Open Graph tags and canonical URL. It runs locally over stdio with no API key or account, requiring only a single command.

Lets Claude Code attach to a running, signed-in Firefox over WebDriver BiDi to control tabs, navigate, screenshot, read pages, click, type, fill forms, evaluate JavaScript, and inspect console/network activity.

Connects an AI assistant to a local Firefox session so it can read pages, interact with forms, manage tabs, and investigate browser issues under user-controlled access rules.

Enables MCP-capable CLIs to operate real, already-logged-in Firefox tabs via a WebExtension and native messaging, without simulated input. Supports navigation, clicking, typing, reading, screenshots, and console/network capture with policy gating and frame awareness.

Enables Claude Code to drive your everyday logged-in browser session — opening and closing tabs, navigating, clicking, typing, scrolling, filling forms, uploading files, taking screenshots, and reading page text, console output and network requests. It runs through a local native-messaging bridge, scoping each client session to its own window behind yours.

It enables AI agents to call a small set of reliable, permission-aware tools generated from an existing website through the Model Context Protocol, without rebuilding the site.

MCP server that fetches remote or local HTML resources and converts them to Markdown, enabling AI clients to summarize or process web content.

Enables AI agents to convert HTML content into clean Markdown, stripping scripts and styles while preserving headings, links, lists, and images, with pay-per-call x402 micropayments and no API keys.

Enables AI apps to control the user’s own signed-in browser in dedicated tabs, using a local command tool for navigation, page interaction, inspection, screenshots, and debugging.

Firefox browser automation via WebDriver BiDi for testing, scraping, and browser control. Supports snapshot/UID-based interactions, network monitoring, console capture, and screenshots.

Enables AI agents to automate and control a real Firefox instance over WebDriver BiDi through 177 browser_* tools spanning web pages, tabs, windows, bookmarks and history, settings, extensions, DevTools, translation, certificates, and more across 17 domains.

Fetches website content and converts it to Markdown format with AI-powered content cleanup, ad removal, and full OpenAPI/Swagger specification support for easy processing by AI assistants.

Provides Firefox browser automation capabilities through Playwright, allowing control of Firefox from MCP-enabled applications with features for basic automation and advanced multi-tab debugging.

Enables Claude to autonomously drive Firefox by combining Claude's planning with Jev's fast element selection for clicks, navigation, and form actions, reducing latency and token usage.

Enables browser automation over MCP using a real Chrome browser with existing profile, supporting real tabs, downloads, cookies, and RPA workflows.

MCP server that bridges opencode into Firefox, enabling page reading, JavaScript execution, and security auditing directly from the terminal.

Enables Claude Code to control Firefox through tools for tabs, navigation, clicks, typing, scrolling, screenshots, page reading, forms, JavaScript, and console/network logs.

Unified MCP server for browser automation (Playwright + CDP + CLI) and bookmark management across Chrome, Firefox, Edge, and Brave, including cross-browser sync, deduplication, and a React dashboard.

Connects to Firefox's Remote Debugging Protocol over TCP, exposing browser DevTools capabilities (JS evaluation, navigation, screenshots, network capture) as tools for LLMs via MCP.

Model Context Protocol server for automating Firefox via WebDriver BiDi, enabling page navigation, snapshots, input, network monitoring, and console debugging for AI agents in MCP clients.

Converts X (Twitter) posts into JSON, PDF, PNG, Markdown, or Slack/Discord messages using public endpoints, no API key or login required.
