vikunja-mcp 0.9.3

MCP server for Vikunja task management

vikunja-mcp

MCP server that gives Claude full access to your Vikunja task management instance.

Works with any Vikunja instance — self-hosted, cloud, or Factumerit.

Features

• Multi-instance support — Connect multiple Vikunja accounts (personal, work, etc.)
• Power queries — "What's overdue?", "Focus mode", "Due this week"
• X-Q (Exchange Queue) — Hand off tasks between Claude Desktop and Claude Code
• Full Vikunja API — Projects, tasks, labels, kanban boards, relations

Quick Start (Factumerit Users)

If you're using Factumerit's hosted Vikunja, the setup is automatic:

1. Your welcome email contains the complete config — just copy it
2. Paste into your Claude Desktop config file (see Config File Location)
3. Restart Claude Desktop
4. Ask Claude: "What's on my todo list?"

Manual Setup

1. Install uv

uv is a fast Python package manager. Install it once:

macOS / Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

Windows (PowerShell):

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

2. Get your Vikunja API token

Go to your Vikunja instance → Settings → API Tokens → Create a token.

Give it a name (e.g., "Claude Desktop") and grant all permissions.

3. Configure Claude Desktop

Add to your Claude Desktop config file:

Single instance:

{
  "mcpServers": {
    "vikunja": {
      "command": "uvx",
      "args": ["vikunja-mcp@latest"],
      "env": {
        "VIKUNJA_URL": "https://your-vikunja-instance.com",
        "VIKUNJA_TOKEN": "your-api-token"
      }
    }
  }
}

Multiple instances:

{
  "mcpServers": {
    "vikunja": {
      "command": "uvx",
      "args": ["vikunja-mcp@latest"],
      "env": {
        "VIKUNJA_INSTANCES": "[{\"name\": \"personal\", \"url\": \"https://vikunja.example.com\", \"token\": \"tk_xxx\"}, {\"name\": \"work\", \"url\": \"https://app.vikunja.cloud\", \"token\": \"tk_yyy\"}]",
        "VIKUNJA_DEFAULT_INSTANCE": "personal"
      }
    }
  }
}

Tip: Use vikunja-mcp@latest to always get the newest version.

Config File Location

OS	Path
macOS	~/Library/Application Support/Claude/claude_desktop_config.json
Windows	%APPDATA%\Claude\claude_desktop_config.json
Linux	~/.config/claude/claude_desktop_config.json

Tip: If the file doesn't exist, create it with just the config above.

4. Restart Claude Desktop

macOS: Cmd+Q, then reopen

Windows: Either:

• Close Claude, open Task Manager (Ctrl+Shift+Esc), end any "Claude" processes, reopen
• Or run: uv cache prune then reopen Claude

Linux: Close and reopen the app

5. Test it

Ask Claude:

"What projects do I have in Vikunja?"

If it works, you'll see your projects listed!

Usage Examples

• "Show me all my tasks due this week"
• "Create a task to review the Q4 report in the Work project"
• "What's blocking the website redesign task?"
• "Move the 'Fix login bug' task to the Done column"
• "Switch to my work instance"
• "List all high-priority tasks across all projects"

Troubleshooting

"No MCP servers found" or tools not appearing

1. Check your config file syntax (valid JSON?)
2. Ensure uv is installed and in your PATH
3. Restart Claude Desktop completely (see above)

"VIKUNJA_URL and VIKUNJA_TOKEN environment variables are required"

Your config is missing the env section. Make sure it looks like:

"env": {
  "VIKUNJA_URL": "https://...",
  "VIKUNJA_TOKEN": "tk_..."
}

"401 Unauthorized" errors

Your API token may have expired or been revoked. Create a new one in Vikunja Settings → API Tokens.

Windows: Claude won't restart properly

Use Task Manager (Ctrl+Shift+Esc) to ensure all Claude processes are ended before reopening. Or run uv cache prune to clear cached environments.

Not getting latest version

Use vikunja-mcp@latest in your args, and run uv cache prune after closing Claude Desktop.

Requirements

• Python 3.10+ (installed automatically by uv)
• A Vikunja instance with API access
• Claude Desktop (or any MCP-compatible client)

Links
