Ask your AI assistant about any Belgian company

1. Run this command in your terminal:
   Terminal Copy

   claude mcp add --transport http checked https://checked.be/mcp --header "X-Api-Key: YOUR_KEY"

2. By default the connection applies to the project you are working in. Add --scope user to use Checked in all your projects.

1. In Claude Desktop, open the settings, choose Developer and then Edit Config. That opens the file claude_desktop_config.json, which you can also open directly at this location:
   • macOS~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows%APPDATA%\Claude\claude_desktop_config.json
2. Add the server under mcpServers. If the file already lists servers, add only the checked block.
   claude_desktop_config.json Copy

   {
     "mcpServers": {
       "checked": {
         "command": "npx",
         "args": [
           "-y",
           "mcp-remote",
           "https://checked.be/mcp",
           "--header",
           "X-Api-Key:${CHECKED_API_KEY}"
         ],
         "env": {
           "CHECKED_API_KEY": "YOUR_KEY"
         }
       }
     }
   }

3. Quit Claude Desktop completely and start it again.

1. Put this in ~/.cursor/mcp.json to use Checked in all your projects, or in .cursor/mcp.json in the folder of a single project. If the file already lists servers, add only the checked block.
   mcp.json Copy

   {
     "mcpServers": {
       "checked": {
         "url": "https://checked.be/mcp",
         "headers": {
           "X-Api-Key": "YOUR_KEY"
         }
       }
     }
   }

Any assistant that supports a remote MCP server over HTTP with a header of its own needs these three facts:

Address

https://checked.be/mcp

Transport

Streamable HTTP

Header

X-Api-Key: YOUR_KEY

In Visual Studio Code it looks like this, in .vscode/mcp.json:

{
  "servers": {
    "checked": {
      "type": "http",
      "url": "https://checked.be/mcp",
      "headers": {
        "X-Api-Key": "YOUR_KEY"
      }
    }
  }
}
