Sharelint MCP server for ChatGPT, Claude, Cursor and VS Code

Let your AI assistant check link previews, AI visibility and app links on any live page, and walk you through the fixes. A free remote MCP server, with no key or sign-up.

Server URL:

https://sharelint.com/api/mcp

Tools

Tool	Checks	Ask it
`check_link_preview`	Link previews in 12 apps: Open Graph and Twitter Card tags, the preview image, and per-app results.	“Why does my link show no image on WhatsApp?”
`check_ai_visibility`	Whether ChatGPT, Claude, Perplexity and other AI bots can reach and read the page.	“Can ChatGPT and Perplexity read my pricing page?”
`check_app_links`	iOS Universal Links and Android App Links, including the copies Apple and Google have cached.	“Why do my links open Safari instead of our iOS app?”
`check_url`	All three checks at once.	“Audit example.com before we launch.”

Add it to your assistant

Claude (web and desktop): Settings, then Connectors, then Add custom connector. Name it Sharelint and paste the server URL.
ChatGPT: in Settings, turn on developer mode, create a custom connector and paste the server URL with no authentication.
Claude Code: run the command below.
Cursor: add the server to ~/.cursor/mcp.json, or .cursor/mcp.json in a project.
VS Code: add the server to .vscode/mcp.json, then start it from the MCP view.
Clients that only run local servers: bridge with mcp-remote.

# Claude Code
claude mcp add --transport http sharelint https://sharelint.com/api/mcp

// ~/.cursor/mcp.json

  "mcpServers": {
    "sharelint": { "url": "https://sharelint.com/api/mcp" }

How it works

The assistant picks a tool from your question and sends the URL. Sharelint fetches the live page the same way the website does, as each app’s crawler and each AI bot, and returns a Markdown report. The report starts with an ordered list of fixes and copy-ready code filled from the page, and links to the interactive report.

Every tool is read-only. Sharelint only reads public pages and never changes anything on your site.
