MCP Setup Guide

Step-by-step setup for connecting SeeLLM MCP to Claude Desktop, Cursor, and other AI assistants.

Generate an API Key

1. Go to app.seellm.com
2. Navigate to Settings > API Keys
3. Click Create API Key
4. Copy the key (starts with sk_live_)

API keys authenticate your MCP connection and scope access to your organization's data.

Claude Desktop

1. Open Claude Desktop settings
2. Go to Developer > Edit Config
3. Add the SeeLLM server:

{
  "mcpServers": {
    "seellm": {
      "url": "https://api.seellm.link/mcp",
      "headers": {
        "Authorization": "Bearer sk_live_your_api_key_here"
      }
    }
  }
}

4. Restart Claude Desktop
5. You should see the SeeLLM tools listed when you start a new conversation

Cursor

1. Open your project root
2. Create .cursor/mcp.json (or edit if it exists):

{
  "mcpServers": {
    "seellm": {
      "url": "https://api.seellm.link/mcp",
      "headers": {
        "Authorization": "Bearer sk_live_your_api_key_here"
      }
    }
  }
}

3. Restart Cursor
4. The SeeLLM tools will be available in the AI pane

Claude Code (CLI)

1. Create .mcp.json in your project root:

{
  "mcpServers": {
    "seellm": {
      "type": "url",
      "url": "https://api.seellm.link/mcp",
      "headers": {
        "Authorization": "Bearer sk_live_your_api_key_here"
      }
    }
  }
}

2. Run claude — the MCP server connects automatically

Custom Streamable HTTP Clients

Use the MCP endpoint below with a client that supports the Streamable HTTP transport:

https://api.seellm.link/mcp
Authorization: Bearer sk_live_your_api_key_here

The client must perform the MCP initialization exchange; a standalone HTTP POST is not a complete integration.

Troubleshooting

Tools not showing up

• Verify your API key is valid and hasn't been revoked
• Check the MCP server URL is exactly https://api.seellm.link/mcp
• Restart your AI assistant after config changes

Authentication errors

• API keys start with sk_live_ — make sure you're using the full key
• The Authorization header format is Bearer sk_live_... (with the space)
• Keys are scoped to your organization — they only access your org's data
