Disban MCP

An official MCP server provided by Disban that allows AI agents to validate email domains for disposable, free, alias, testing, or parked status. It exposes tools to check single or batch email domains and retrieve usage statistics, helping prevent fraud in sign-ups and referrals.

Endpoint and access

No sign-in: your client connects and lists tools immediately, with no account or key.

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 a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http disban-mcp https://disban.io/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 disban-mcp --url https://disban.io/mcp

Cursor

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

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.
Cline configuration
{
  "mcpServers": {
    "disban-mcp": {
      "type": "streamableHttp",
      "url": "https://disban.io/mcp",
      "disabled": false
    }
  }
}

VS Code

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