@celiums/mcp

140,000+ expert knowledge modules for AI coding assistants. One MCP connection.

Celiums is an MCP server that gives your AI coding assistant access to a massive library of expert knowledge modules — from React to Kubernetes, from HIPAA compliance to financial modeling.

Works with: Claude Code, Cursor, VS Code (Continue), Windsurf, and any MCP-compatible client.

Quick Start

1. Create your account

npx @celiums/mcp --email [email protected]

You'll receive a 6-digit verification code by email. Enter it to get your API key.

Or sign up at celiums.io/signup.

2. Add to your IDE

Claude Code — add to ~/.claude/claude_desktop_config.json:

{
  "mcpServers": {
    "celiums": {
      "command": "npx",
      "args": ["@celiums/mcp"],
      "env": {
        "CELIUMS_API_KEY": "sk-celiums_YOUR_KEY_HERE"
      }
    }
  }
}

Cursor — add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "celiums": {
      "command": "npx",
      "args": ["@celiums/mcp"],
      "env": {
        "CELIUMS_API_KEY": "sk-celiums_YOUR_KEY_HERE"
      }
    }
  }
}

VS Code + Continue — add to ~/.continue/config.json:

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "stdio",
          "command": "npx",
          "args": ["@celiums/mcp"],
          "env": {
            "CELIUMS_API_KEY": "sk-celiums_YOUR_KEY_HERE"
          }
        }
      }
    ]
  }
}

Windsurf — add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "celiums": {
      "command": "npx",
      "args": ["@celiums/mcp"],
      "env": {
        "CELIUMS_API_KEY": "sk-celiums_YOUR_KEY_HERE"
      }
    }
  }
}

3. Use it

Ask your AI assistant:

Use celiums to find best practices for React error boundaries

Tools

| Tool | What it does | |------|-------------| | forage | Search 140,000+ modules by keyword | | absorb | Load a complete knowledge module | | synthesize | AI applies module methodology to your specific task | | sense | Get intelligent module recommendations | | bloom | Generate complete documents (blog posts, SOPs, reports) | | map_network | Browse all modules by category | | account_status | Check your plan, usage, and limits (free) | | account_upgrade | Get a Stripe payment link to upgrade (free) | | account_buy_credits | Buy credit packs (free) | | account_usage | View your request history (free) |

Direct API Access

You can also call the API directly:

curl -X POST https://api.celiums.io/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer sk-celiums_YOUR_KEY_HERE" \
  -d '{
    "jsonrpc": "2.0",
    "method": "tools/call",
    "params": {
      "name": "forage",
      "arguments": {"query": "kubernetes deployment patterns"}
    },
    "id": 1
  }'

Plans

| Plan | Price | Requests/day | |------|-------|-------------| | Free | $0 | 50 | | Pro | $39/mo | 2,000 | | Network | $99/mo | 10,000 (5 seats) |

Upgrade from your IDE: just ask your AI assistant to "upgrade my celiums plan to pro".

Configuration

The MCP client resolves your API key in this order:

1. --api-key flag
2. CELIUMS_API_KEY environment variable
3. Saved key in ~/.celiums/credentials.json
4. Interactive onboarding (prompts for email)
