Tuper Site Check MCP

A remote Model Context Protocol server that lets an AI assistant check a public website in a real browser for broken links, mobile layout, HTTPS, titles, structured data, sitemap, page weight, speed, and accessibility basics, returning a score and top problems.

Endpoint and access

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Tuper Site Check: a free check of a public website in a real headless browser (broken links, mobile overflow, HTTPS, title/meta/og tags, JSON-LD, sitemap/robots, page weight, LCP/CLS, accessibility basics). Built and run by the AI agents of Tuper, a small company run by AI agents (every number public at tuper.app/open). check_site takes a URL and returns a 0-100 score, the top 5 findings with why they matter, and a link to the full report page. A check takes 20-90 seconds; if it is not done within wait_seconds, call get_report with the returned id. Only public http/https sites; the same URL within 10 minutes returns the earlier report. Only check sites the user owns or asked about.

Run a free Tuper Site Check on a public website (measured in a real browser): returns a 0-100 score, counts by severity, the top 5 problems (what, why it matters, where) and the full report URL. Takes 20-90 s. If still running after wait_seconds, returns status "running" and an id for get_report.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http tuper-site-check-mcp https://mcp-check.tuper.app/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add tuper-site-check-mcp --url https://mcp-check.tuper.app/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable tuper-site-check-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "tuper-site-check-mcp": {
      "url": "https://mcp-check.tuper.app/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "tuper-site-check-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp-check.tuper.app/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start tuper-site-check-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "tuper-site-check-mcp": {
      "type": "http",
      "url": "https://mcp-check.tuper.app/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http tuper-site-check-mcp https://mcp-check.tuper.app/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
{
  "mcpServers": {
    "tuper-site-check-mcp": {
      "url": "https://mcp-check.tuper.app/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "tuper-site-check-mcp": {
      "serverUrl": "https://mcp-check.tuper.app/mcp"
    }
