"Open Collective" matching MCP servers:

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.

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.

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.

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.

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.

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

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

Open-source MCP server exposing the Agent402.Tools catalog: 500+ deterministic 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

Browser automation MCP server that uses a real browser to give agents eyes and hands—open pages, click, fill, screenshot, and run scripts via accessibility-tree snapshots.

Enables Claude to browse stores, search products, manage the cart, and open checkout on Rappi Chile through natural language, automating grocery and delivery purchases.

A local, open-source MCP server that enables AI clients to control multiple isolated Chromium browser sessions concurrently, with explicit session and page addressing and independent state.

Enables AI hosts to generate and open Mermaid diagram links in Markdown files, providing tools for syncing, listing, and injecting diagrams via the Mermaid.ai editor.

Open-source MCP server that gives AI agents access to 100+ web applications through the user's authenticated browser session. No API keys, no screenshots, no DOM scraping — talks directly to web app internal APIs via a Chrome extension. Supports Slack, Discord, GitHub, Jira, Notion, Reddit, X, and 100+ more services with ~2,000 tools. Works with Claude Code, Cursor, Windsurf, and any MCP client.

Enables MCP clients to open and close applications, files, and folders on a Windows machine, manage running apps and File Explorer windows, control Chrome tabs, and perform system actions like shutdown and restart.

An MCP server that gives local LLMs access to Google search, live feeds, YouTube transcriptions, OCR, and more — all without API keys, using headless Chromium and open-source models.

An open-source MCP server that provides AI assistants with structured, token-efficient web context through specialized tools for searching, scraping, and deep research. It streamlines developer workflows by delivering optimized Markdown content directly into IDEs like VS Code, eliminating the need for manual browser switching.
