MCP Quick Start

Connect your AI assistant to Moxn Documents over MCP

This guide walks you through connecting your AI assistant to Moxn Documents over MCP so it can search, read, and write documentation.

For CLI-based setup (API key, no MCP), see CLI Quick Start.

Prerequisites

• A Moxn account (get one at moxn.dev)
• An AI assistant that supports MCP:
  • Web apps: Claude.ai, ChatGPT, Gemini
  • Cloud environments: Claude Cowork
  • CLI tools: Claude Code, Gemini CLI
  • Desktop apps: Cursor, Claude Desktop, ChatGPT Desktop

No coding required. This setup involves copying a configuration snippet — that’s it.

Step 1: Get Your Configuration

1. Sign in to moxn.dev
2. Go to Knowledge Base
3. Click MCP Setup to expand the configuration panel
4. Copy the configuration snippet for your connection type (stdio or http)

Local (stdio) — runs on your machine via npx:

{
  "mcpServers": {
    "knowledge-base": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "@moxn/mcp-kb",
        "--workspace=your-workspace-slug"
      ]
    }
  }
}

Remote (http) — connects directly to Moxn’s servers:

{
  "mcpServers": {
    "knowledge-base": {
      "type": "http",
      "url": "https://your-workspace-slug.moxn.dev/api/mcp/http"
    }
  }
}

Step 2: Add to Your AI Assistant

Choose your assistant below:

Claude (web)

Claude.ai supports MCP servers through its Integrations settings.

1. Go to claude.ai
2. Click your profile icon → Settings → Integrations
3. Click Add Integration and select MCP
4. Enter the remote URL:
   https://your-workspace-slug.moxn.dev/api/mcp/http
   
5. Save the integration

Replace your-workspace-slug with your actual workspace slug (visible in your Moxn dashboard URL).

Once connected, you can use Moxn tools in any Claude.ai conversation.

ChatGPT (web)

ChatGPT supports MCP connectors through its settings.

Requires a Plus or Pro subscription with developer mode enabled.

1. Go to chatgpt.com
2. Open Settings → Apps & Connectors → Advanced settings
3. Enable Developer mode
4. Click Create under connectors
5. Fill in:
   • Name: Moxn Documents
   • Description: Search, read, and write documentation
   • URL: https://your-workspace-slug.moxn.dev/api/mcp/http
6. Save the connector

Replace your-workspace-slug with your actual workspace slug.

To use it, click the + button in a new chat, select More, then choose Moxn Documents from your connectors.

Limitation: The upload_url tool is not fully supported with remote connections. Avoid file uploads when using ChatGPT.

Gemini (web)

Google Gemini supports MCP through Google AI Studio.

1. Go to aistudio.google.com
2. Open a project and go to Tools → MCP Servers
3. Add a new server with the remote URL:
   https://your-workspace-slug.moxn.dev/api/mcp/http
   
4. Save the configuration

Replace your-workspace-slug with your actual workspace slug.

Claude Cowork

Claude Cowork runs in a cloud VM that cannot execute local commands like npx. Use the remote HTTP connection instead:

{
  "mcpServers": {
    "knowledge-base": {
      "type": "http",
      "url": "https://your-workspace-slug.moxn.dev/api/mcp/http"
    }
  }
}

Replace your-workspace-slug with your actual workspace slug (visible in your Moxn dashboard URL).

Limitation: The upload_url tool is not fully supported in HTTP mode. Avoid file uploads when using Claude Cowork.

Claude Code

Add the configuration to .mcp.json in your project root:

{
  "mcpServers": {
    "knowledge-base": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "@moxn/mcp-kb",
        "--workspace=your-workspace-slug"
      ]
    }
  }
}

Claude Code will automatically detect and connect to the server.

Cursor

Add the configuration to your Cursor MCP settings:

1. Open Cursor
2. Go to Settings → MCP
3. Click Add new MCP server
4. Add this configuration:

{
  "mcpServers": {
    "knowledge-base": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "@moxn/mcp-kb",
        "--workspace=your-workspace-slug"
      ]
    }
  }
}

Cursor will automatically connect to the server.

Claude Desktop

Mac

1. Open Claude Desktop
2. Click Claude in the menu bar → Settings
3. Select the Developer tab
4. Click Edit Config

This opens claude_desktop_config.json in your text editor. If the file is empty or just has {}, replace it with your configuration from Step 1.

If you already have other MCP servers configured, add the knowledge-base entry inside the existing mcpServers object:

{
  "mcpServers": {
    "existing-server": { ... },
    "knowledge-base": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "@moxn/mcp-kb",
        "--workspace=your-workspace-slug"
      ]
    }
  }
}

5. Save the file
6. Quit and reopen Claude Desktop

Windows

1. Open Claude Desktop
2. Click the hamburger menu (☰) → Settings
3. Select the Developer tab
4. Click Edit Config

This opens claude_desktop_config.json in Notepad. Add your configuration as described above.

5. Save the file
6. Close and reopen Claude Desktop

Verify It’s Working

After restarting Claude Desktop, you should see a hammer icon in the bottom-right corner of the chat window. This indicates MCP servers are connected.

Click the + button at the bottom of the chat, then select Connectors to see your connected servers.

ChatGPT Desktop

ChatGPT Desktop uses a GUI-based setup instead of a config file.

Requires Developer Mode. You’ll need a ChatGPT Plus or Pro subscription with developer mode enabled.

1. Open ChatGPT Desktop
2. Go to Settings → Apps & Connectors → Advanced settings
3. Enable Developer mode
4. Click Create under connectors
5. Fill in:
   • Name: Moxn Documents
   • Description: Search, read, and write documentation
   • URL: https://your-workspace-slug.moxn.dev/api/mcp/http
6. Save the connector

Replace your-workspace-slug with your actual workspace slug (visible in your Moxn dashboard URL).

To use it, click the + button in a new chat, select More, then choose Moxn Documents from your connectors.

Limitation: The upload_url tool is not fully supported with remote connections. Avoid file uploads when using ChatGPT Desktop.

Gemini CLI

The Gemini CLI supports MCP servers through its configuration file.

1. Create or edit ~/.gemini/settings.json
2. Add the MCP server configuration:

{
  "mcpServers": {
    "knowledge-base": {
      "command": "npx",
      "args": [
        "@moxn/mcp-kb",
        "--workspace=your-workspace-slug"
      ]
    }
  }
}

See the Gemini CLI MCP documentation for more details.

Other Hosts

For other MCP-compatible tools, you’ll need either:

Local connection (if your tool can run npx):

{
  "mcpServers": {
    "knowledge-base": {
      "type": "stdio",
      "command": "npx",
      "args": ["@moxn/mcp-kb", "--workspace=your-workspace-slug"]
    }
  }
}

Remote connection (if your tool runs in a VM or browser):

{
  "mcpServers": {
    "knowledge-base": {
      "type": "http",
      "url": "https://your-workspace-slug.moxn.dev/api/mcp/http"
    }
  }
}

Not sure which to use? See Understanding Connection Types below.

Understanding Connection Types

Not sure which setup to use? Here’s the difference:

Type	How It Works	Apps That Use It
Local (stdio)	Runs on your machine via npx	Claude Code, Cursor, Claude Desktop, Gemini CLI
Remote (http)	Connects to Moxn’s servers	Claude.ai, ChatGPT, Gemini, Claude Cowork, ChatGPT Desktop

Local is better when available. It supports all features including file uploads, and keeps data flowing through your machine.

Remote is required for web and cloud environments. Web apps and cloud VMs can’t execute local commands. The upload_url tool doesn’t work reliably in remote mode.

Using Multiple AI Assistants

If you use several AI tools (e.g., Claude Code on your laptop and Claude.ai in the browser), you can configure both connections. Use different server names so each tool knows which to use:

{
  "mcpServers": {
    "knowledge-base": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "@moxn/mcp-kb",
        "--workspace=your-workspace-slug"
      ]
    },
    "knowledge-base-remote": {
      "type": "http",
      "url": "https://your-workspace-slug.moxn.dev/api/mcp/http"
    }
  }
}

Step 3: Authenticate

The first time you use Moxn Documents with your AI:

1. Ask your AI something like “List my Moxn documents”
2. A browser window will open for authentication
3. Sign in with your Moxn account
4. Return to your AI assistant

Your session persists across restarts — you only need to authenticate once.

Try It Out

Once connected, try these prompts with your AI:

Read documents:

“What documents do I have in Moxn?”

“Read the API documentation from my knowledge base”

Create content (on a branch):

“Create a new document called ‘Meeting Notes’ with today’s discussion points”

“Update the onboarding guide to include the new security requirements”

Your AI will create a branch for any changes. You can review and merge in the Moxn web app.

Troubleshooting

Claude Desktop doesn't show the hammer icon

• Make sure you saved the config file and restarted Claude Desktop completely (not just closed the window)
• Check that the JSON is valid (no trailing commas, matching braces)
• On Mac, you can find the config file at ~/Library/Application Support/Claude/claude_desktop_config.json
• On Windows, it’s at %APPDATA%\Claude\claude_desktop_config.json

Authentication window doesn't open

• Make sure your default browser isn’t blocking popups from Moxn
• Try running the MCP server manually to see errors: npx @moxn/mcp-kb --workspace=your-workspace-slug

'npx' is not recognized

You need Node.js installed. Download it from nodejs.org (choose the LTS version).

After installing, restart your terminal/computer and try again.
