Lodestone

Lodestone

A hosted remote MCP server. One URL gives Claude, ChatGPT, Gemini, Cursor or any other MCP client 51 tools across 21 services: WhatsApp, Telegram and Signal messaging, email from any IMAP inbox, live Airbnb, Amazon, Booking.com, Google Flights, Google Maps and Reddit data, social search, Meta Ads, cross-posting, and image and video generation.

Nothing to install and nothing to run. This repository holds the public connection docs and registry metadata; the server itself is a hosted service at https://lodestone.studiocorsair.com.

Connect

Claude (web, desktop, mobile): Settings → Connectors → Add custom connector → paste the endpoint → sign in when prompted.

ChatGPT: enable Developer Mode, then Settings → Connectors → Create → paste the endpoint.

Cursor / VS Code / Windsurf / Cline: add a remote server entry:

{
  "mcpServers": {
    "lodestone": {
      "url": "https://lodestone.studiocorsair.com/mcp"
    }
  }
}

The client opens a browser window for sign-in on first use. Clients that only support stdio can bridge with npx mcp-remote https://lodestone.studiocorsair.com/mcp.

Full setup per client: https://lodestone.studiocorsair.com/docs.html

What needs your own credentials

Web search, social search, the Meta Ad Library and generation run on Lodestone's provider keys at no cost to you (generation is capped at 5 per provider per month on the free plan). Anything that acts on your own accounts (email, messaging, Meta Ads, Telegram bots, Typefully) uses credentials you connect at https://lodestone.studiocorsair.com/account. They are encrypted with AES-256-GCM at rest and never logged. Tools marked [WRITE] change something real, and good clients ask before calling them.
