Claude Desktop & Web

Use Docsumo MCP in the Claude apps.

📘
Why this guide uses a bridge
Custom connectors in the Claude apps currently authenticate remote servers with OAuth only — they can't attach a custom API-key header. Until Docsumo MCP ships OAuth sign-in, connect Claude Desktop through the mcp-remote bridge below (it runs locally and adds your key to each request). Claude Web will be supported once OAuth sign-in is available.

Prerequisites

Claude Desktop with a plan that supports MCP servers
Node.js 18+ (node --version)
Your Docsumo API key from Settings → API & Webhooks

Setup

Open Settings → Developer → Edit Config. This opens claude_desktop_config.json.
Add the Docsumo server (replace YOUR_API_KEY):

{
  "mcpServers": {
    "docsumo": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://mcp.docsumo.com/mcp",
        "--header",
        "Authorization: Bearer ${DOCSUMO_API_KEY}"
      ],
      "env": {
        "DOCSUMO_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

Save the file and fully restart Claude Desktop (quit from the system tray/menu bar, then reopen).

🚧
Windows note
If the connection fails on Windows, spaces in header arguments can be mangled. Use "Authorization:Bearer ${DOCSUMO_API_KEY}" (no space after the colon) — mcp-remote accepts both forms.

Verify

Click the tools icon (🔨) in a new chat — the Docsumo tools should be listed. Then try:
