Connect Claude Desktop to the Bland MCP server

The Bland MCP server is a hosted, streamable-HTTP server. Every client needs the same two values:

URL: https://api.bland.ai/v1/mcp
Header: Authorization: Bearer YOUR_BLAND_API_KEY

Setup

Prefer the Bland plugin, which installs into Claude Desktop and stores the key for you. If your organization has access to Claude’s request-header authentication beta, add a custom connector with the server URL above, choose No sign-in, and add an Authorization request header with the full value Bearer YOUR_BLAND_API_KEY. If Request headers is unavailable, use the stdio bridge below. Install Node.js 22+ with npm first, then add this entry to claude_desktop_config.json (Settings → Developer → Edit Config). Replace org_your_key_here with your API key:

{
  "mcpServers": {
    "bland": {
      "command": "npx",
      "args": [
        "-y", "mcp-remote", "https://api.bland.ai/v1/mcp",
        "--header", "Authorization:${AUTH_HEADER}"
      ],
      "env": { "AUTH_HEADER": "Bearer org_your_key_here" }
    }
  }
}

Keep the entire Bearer ... value in AUTH_HEADER. This avoids the Windows argument-spacing issue documented by mcp-remote. Restart Claude Desktop after saving.
