"Open Collective" matching MCP servers:

Enables Claude to delegate web search, page reading, text drafting, and parallel multi-model image generation to cheaper helper models on any OpenAI-compatible backend. Claude stays in charge of planning and final decisions while consuming fewer of its own tokens.

Web search using free multi-engine search (NO API KEYS REQUIRED) — Supports Bing, Baidu, DuckDuckGo, Brave, Exa, and CSDN.

Enables AI agents to control the user's Chrome or Firefox browser, leveraging existing sessions for tasks requiring authentication and user handoff.

Enables web crawling and content extraction from web pages, supporting multiple output formats like text, markdown, XML, and JSON, with robots.txt compliance and rate limiting.

Enables AI agents to automate both web browsers and native desktop applications through a unified interface, supporting tasks like browsing, clicking, typing, and file clipboard operations via exposed MCP tools.

MCP server that connects AI assistants to a live Ketcher window, the open-source web-based chemical structure editor. Draw, edit, and organize structures directly in the canvas you have open.

Enables AI agents to interact with a signed-in Gemini web account through a local stdio MCP server for status, capabilities, models, prompts, history, conversations, memory, usage, and downloads.

Enables AI agents to drive your own signed-in ChatGPT web account — asking questions, continuing chats, attaching files, toggling thinking or web search, creating images, transcribing recordings of any length, reading replies aloud, and managing conversations, memories and projects. It runs against a local Chrome tab on chatgpt.com and reports live progress and step-named errors back to the client.

MCP server that gives any LLM a managed Docker workspace with live browser, terminal, code execution, document skills, and autonomous sub-agents.

A proxy-aware MCP server that enables web searching across multiple engines and automated markdown content extraction from webpages. It features a deep research agent for recursive searching and synthesis, supporting complex network environments through SOCKS5 and HTTP proxies.

Enables AI agents to control Chrome, Edge, Brave and other Chromium browsers through an extension and native messaging host, exposing a Claude-in-Chrome-compatible tool set for real clicks, typing, screenshots, accessibility-tree reading, page text, form filling, JavaScript execution, console and network inspection, file uploads and GIF recording. Agent sessions run in isolated tab groups with per-site permission prompts, activity logging and a global stop control.

Enables AI assistants to list, search, add, tag, remove, validate, and export locally stored contacts, and to extract emails, phone numbers, and social links from provided text or HTML.

A shared distillation cache for AI agents — clean-crawl a URL once, distill it to token-optimal markdown, and serve it content-addressed across every agent (~73–89% fewer tokens). Includes a collective-notes layer and cutoff-aware change detection.

An open-source MCP server providing AI agents with neural web search via Exa and tiered web fetch (Exa, local browser, Firecrawl) as a drop-in replacement for built-in web tools, preserving provenance and guarding against SSRF.

Open-source browser automation API with anti-detection for AI agents, web scraping, and automation, providing undetectable Chrome via MCP and REST API with Cloudflare bypass.

Enables AI agents to read any URL by using an escalating open-source unlocker to bypass common bot walls, returning clean Markdown content.

Enables Claude to search products, build a shopping cart on Selver.ee, and open it in the browser for checkout.

Enables AI agents to open, read, and act on live web pages through verified browser actions, including filling forms, extracting data, debugging pages, and handling bot walls.

Enables an assistant to search and read AnkiWeb's shared-deck catalogue, download decks as .apkg files or Markdown, list the decks synced to your account, and publish a deck after a confirmed preview, all through your own AnkiWeb session. It can reuse a signed-in session from a local Chromium browser or open a login window, keeping credentials out of the server.

Open-source MCP server exposing the Agent402.Tools catalog: 500+ pay-per-call tools for AI agents, including browser rendering, web search, PDFs, OCR, LLM inference, code execution, live financial/crypto/macro data, SEC EDGAR, and wallet-keyed memory. Free via proof-of-work, or pay per call in USDC across ten chains via the x402 protocol. No API keys, no signups

Scans any website and produces an Agent Readiness Report scored on the open ASO framework.

Free open-source CLI and read-only MCP tool from Advisors AI (advisorsai.ai): give it one public URL and it lists which machine-readable basics are present or missing (title, meta description, structured data, one h1, canonical, robots policy for AI crawlers, llms.txt, sitemap). No API key, no account, nothing stored.

Drive the real, logged-in Chrome you already have open — cross-platform, token-budgeted reading (90%+ savings), and 24/7 headless Ubuntu support.

An open-source MCP server that lets any coding agent operate your computer like a person does—reading the UI through accessibility trees, clicking and typing in the background, showing an agent pointer, zooming into regions, and driving your signed-in Chrome on macOS, Windows, and Linux.

provides direct access to your browser's open tabs content. No additional fetching or authentication required - simply access what you're already viewing.

Tabhand lets AI coding agents use your real, signed-in Chrome, in background tabs that never steal your focus. Free, open source, runs locally.

Lets OpenCode check whether Arc is open on Windows and navigate it to absolute HTTP(S) URLs from WSL2, even when another browser is the Windows default.

Enables a coding agent to read web pages through the user's own real, logged-in Chrome profile instead of a server-side fetcher, so pages behind logins, SSO, or bot checks load successfully. Exposes tools to extract readable text from the active tab and to open a URL in a background tab with real cookies, read it, then close it.

Lets Claude and other MCP clients generate and edit images with your own signed-in ChatGPT account in a background Chrome tab. No API key, no open ports; right-click reference collections and a gallery side panel. Windows + Chrome.

PageSift is an open-source Rust MCP server that crawls websites and extracts clean Markdown and structured content from web pages, PDFs, and Office documents. It supports adaptive rendering, query-focused crawling, and batch extraction for AI agents and RAG pipelines.
