Contextium MCP Server

Give your AI assistant persistent, searchable access to your team's docs, SOPs, coding standards, and agent configs — no copy-pasting.

Contextium is a central knowledge store that AI assistants can read directly via MCP. Connect Claude, Cursor, Windsurf, or any MCP-compatible client and your AI will automatically follow your team's guidelines, load the right context for each task, and stay consistent across every session.

Why Contextium?

Without a shared knowledge store, every AI session starts from scratch. You paste in the same coding standards, re-explain the same architecture, and hope the AI stays consistent. Contextium solves this at the source.

• Context libraries — store SOPs, coding standards, architecture docs, and API references
• Agents — pre-configured AI personas with skills and constraints baked in
• Skills — reusable knowledge modules the AI can load on demand
• Workflows — named context sets that load everything needed for a task in one command
• Marketplace — install community-built agents and skills instantly

Once connected, Claude pulls in your team's knowledge automatically. You stop repeating yourself.

Quick Start — Remote MCP (Recommended)

No installation required. Add the hosted Contextium MCP server to your AI client and authenticate once.

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "contextium": {
      "type": "sse",
      "url": "https://mcp.contextium.io/sse"
    }
  }
}

Restart Claude Desktop. A browser window will open on first use to authenticate your Contextium account.

Claude Code (CLI)

claude mcp add contextium --transport sse https://mcp.contextium.io/sse

Cursor

{
  "mcpServers": {
    "contextium": {
      "url": "https://mcp.contextium.io/sse"
    }
  }
}

VS Code (Copilot)

{
  "mcp": {
    "servers": {
      "contextium": {
        "type": "sse",
        "url": "https://mcp.contextium.io/sse"
      }
    }
  }
}

Option 2: Local MCP (Self-hosted)

Run the MCP server locally via npm for offline access or self-hosting.

# Authenticate and configure
npx @contextium/mcp-server@latest setup

Then add to your Claude Desktop config:

{
  "mcpServers": {
    "contextium": {
      "command": "npx",
      "args": ["-y", "@contextium/mcp-server@latest"]
    }
  }
}

Auth commands

npx @contextium/mcp-server setup      # Initial setup — opens browser to authorize
npx @contextium/mcp-server status     # Check connection and active workspace
npx @contextium/mcp-server profiles   # Manage multiple accounts
npx @contextium/mcp-server logout     # Sign out

What Claude Can Do

Once connected, you interact naturally — Contextium handles the context loading:

"Load our React coding standards and review this component for compliance"

"What are our team's rules for writing API endpoints?"

"Load the Backend workflow and help me scaffold a new service"

"Find all documentation related to our authentication flow"

"Install the code-reviewer agent from the marketplace"

"Notify the team about this new spec I just created"

"Notify Sarah about this workflow — just her, not everyone"

Troubleshooting

OAuth login not appearing (Remote MCP) Ensure your client supports remote MCP with OAuth: Claude Desktop 0.7+, Cursor 0.42+. Restart after updating config.

"Not authenticated" error (Local MCP)

npx @contextium/mcp-server status
npx @contextium/mcp-server setup

Claude Desktop not seeing tools

1. Check config file syntax (valid JSON, correct path)
2. Ensure npx is in your PATH
3. Restart Claude Desktop completely
4. Check logs: ~/Library/Logs/Claude/mcp*.log

API timeout Check https://status.contextium.io or verify your token with npx @contextium/mcp-server status.
