Features • Quick Start • Installation • Tools • Examples • Contributing

What is this?

A Model Context Protocol (MCP) server that connects AI assistants like Claude to Teamleader Focus - the all-in-one CRM, invoicing, and project management platform.

Instead of clicking through menus, just ask:

"Find all open deals for Acme Corporation"
"Create an invoice for 20 hours of consulting at €125/hour"
"Schedule a meeting with Sarah from TechStart next Tuesday at 2pm"
"Log 3 hours to the website project with description: frontend development"

{
  "mcpServers": {
    "teamleader": {
      "command": "npx",
      "args": ["-y", "teamleader-mcp"]
    }
  }
}

3. Start Using!

Restart Claude Desktop and ask: "What Teamleader tools do you have access to?"
