Usage

1. Get your Toggl API Token

Go to https://track.toggl.com/profile and copy your API token.

2. Run the MCP server

export TOGGL_API_TOKEN="your_token_here"
tempus-mcp

3. Configure your MCP client

Claude Desktop:

{
  "mcpServers": {
    "tempus": {
      "command": "tempus-mcp",
      "env": {
        "TOGGL_API_TOKEN": "your_token_here"
      }
    }
  }
}

Opencode / other MCP clients (recommended): If your MCP client does not reliably pass environment variables through npx, pass the token directly via CLI arguments:

{
  "mcpServers": {
    "tempus": {
      "command": ["npx", "-y", "tempus-mcp", "--token", "your_token_here", "--workspace-id", "12345678"]
    }
  }
}

Other MCP clients: The server uses stdio transport, compatible with any MCP client.
