My AI assistant can't reach Blinkhop. What should I check?

Check that your client uses the exact URL https://mcp.blinkhop.com/mcp with the HTTP transport, restart the client, and look at the status page. Most connection problems come from a typo in the URL, the wrong transport or a config file in the wrong place.

MCP connection checklist

1. Status. The status page shows live checks of redirects, the API and the MCP server.
2. URL. It must be exactly https://mcp.blinkhop.com/mcp, with https and the /mcp path.
3. Transport. Blinkhop is a remote server that uses Streamable HTTP, so there is nothing to install or run locally. In Claude Code, use --transport http. In VS Code, set "type": "http".
4. Config keys. Cursor uses mcpServers with url. VS Code uses servers with type and url. Windsurf uses mcpServers with serverUrl.
5. File location. Cursor reads ~/.cursor/mcp.json, VS Code reads .vscode/mcp.json in your project, and Windsurf reads ~/.codeium/windsurf/mcp_config.json. One missing comma or bracket makes the whole file invalid.
6. ChatGPT. Turn on developer mode under Settings → Connectors → Advanced before you add the URL.
7. Restart. Restart or reload your client after you change its configuration.
8. Limits. The server allows 120 calls per minute and 5,000 per day per IP address. If you hit a limit, wait and try again.
9. Network. A company proxy or firewall can block mcp.blinkhop.com. Tor and VPNs are fine: there are no captchas or bot walls in front of the MCP server.

Test the server from a terminal

If you open the URL in a browser, you may see an error instead of a page. That’s expected, because MCP clients talk to the server with POST requests. To test the server, ask it for its tools:

curl https://mcp.blinkhop.com/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

The response should list shorten_link, shorten_links and expand_link. If it does, the server is reachable and the problem is in your client’s setup. How do I connect Blinkhop to Claude, ChatGPT or Cursor? has the exact steps for each client.
