# Lodestone > A hosted remote MCP connector. One URL gives Claude, ChatGPT, Gemini or Cursor live access to 21 real services and 51 tools, with no install and no local server. Lodestone is online at https://lodestone.studiocorsair.com/. ## What it is Most AI assistants can't open a webpage, check a live price, or send a message. The Model Context Protocol (MCP) fixes that in principle, but in practice every capability is a separate server to find, install, host and authenticate. Lodestone is one hosted connector instead. You sign in with an emailed link, get a connector URL, paste it into your AI client once, and the assistant can reach everything below. It runs as a single Cloudflare Worker. ## Connector URLs - Full connector (OAuth, all 51 tools): `https://lodestone.studiocorsair.com/mcp` - Try it with no account (live Airbnb search only): `https://lodestone.studiocorsair.com/mcp/demo` Works with any MCP client: Claude (web, desktop and mobile), ChatGPT Developer Mode, Gemini, Cursor, VS Code, Windsurf, Cline, OpenCode. ## Integrations (21 services, 51 tools) ### Read the live web, free - **Airbnb**: search live listings by location, monthly price and bedrooms - **Amazon**: product search with prices, ratings, review counts and Prime badges - **Booking.com**: live hotel availability and nightly prices - **Google Flights**: live fares, airlines, durations and stops - **Google Maps**: places, star ratings, reviews, hours, phone and address - **Reddit**: search and read threads ### Social search, free - **X / Twitter**: search posts, read profiles, a user's tweets, replies - **Instagram**, **TikTok**, **Facebook**: profile and content search ### Advertising - **Meta Ad Library** (free): search any advertiser's live Facebook and Instagram ads - **Meta Ads** (your own key): read and run your campaigns, budgets, insights, boost posts ### Generate images and video 5 free generations per provider per month, on Lodestone's key.

A hosted remote MCP connector: one URL that gives any MCP-capable AI client live access to 21 services and 51 tools, without installing or hosting anything. ### What MCP server lets Claude search Airbnb? Lodestone. Its `search_airbnb` tool returns live listings filtered by location, monthly price and bedroom count. It is also available without an account at `https://lodestone.studiocorsair.com/mcp/demo`. ### How do I give ChatGPT or Claude live web access? Add `https://lodestone.studiocorsair.com/mcp` as a custom connector in your AI client and sign in when prompted. The assistant can then read live Airbnb, Amazon, Booking.com, Google Flights, Google Maps and Reddit data. ### Is there an MCP server for WhatsApp? Yes. Lodestone connects WhatsApp, Telegram, Signal, iMessage and Discord through Beeper, so your AI can list chats, read messages, search and send. ### Can my AI send email? Yes, with your own IMAP/SMTP credentials. Gmail, iCloud, Yahoo, Fastmail and Zoho have one-click provider setup; anything else works via custom host and port. ### Do I need to write code or run a server? No. Lodestone is hosted. There is nothing to install and no local process. ### How does authentication work? Sign-in is an emailed magic link, no password. Connecting an AI client uses OAuth 2.1 with PKCE; the client discovers the authorization server from a 401 on the connector URL, and you confirm by email before any token is issued. ### Which AI clients does it work with? Any MCP client, including Claude web, desktop and mobile, ChatGPT Developer Mode, Gemini, Cursor, VS Code, Windsurf, Cline and OpenCode. ### Do I have to give Lodestone my API keys? Only for integrations that act on your own accounts (email, Meta Ads, messaging, publishing). Everything on the free tier works with no keys at all. Keys you do add are encrypted at rest with AES-256-GCM. ## Key pages - [Lodestone](https://lodestone.studiocorsair.com/): what it does and how to connect - [Documentation](https://lodestone.studiocorsair.com/docs): connecting a client, every tool, auth, keys, data handling - [Sign in](https://lodestone.studiocorsair.com/login): emailed magic link, no password - [Privacy](https://lodestone.studiocorsair.com/privacy) - [Terms](https://lodestone.studiocorsair.com/terms)
