macOS/Windows:

claude mcp add task-manager -s user \
  --env "TASK_MANAGER_HOST=host.docker.internal" \
  --env "TASK_MANAGER_PORT=8080" \
  --env "TASK_MANAGER_TIMEOUT=30" \
  --env "USE_MOCK_CLIENT=false" \
  -- docker run -i --rm \
    -e TASK_MANAGER_HOST \
    -e TASK_MANAGER_PORT \
    -e TASK_MANAGER_TIMEOUT \
    -e USE_MOCK_CLIENT \
    task-manager-mcp:latest

Linux:

claude mcp add task-manager -s user \
  --env "TASK_MANAGER_HOST=localhost" \
  --env "TASK_MANAGER_PORT=8080" \
  --env "TASK_MANAGER_TIMEOUT=30" \

  -- docker run -i --rm --network=host \
    -e TASK_MANAGER_HOST \
    -e TASK_MANAGER_PORT \
    -e TASK_MANAGER_TIMEOUT \
    -e USE_MOCK_CLIENT \
    task-manager-mcp:latest

Mock Mode (for testing):

claude mcp add task-manager-mock -s user \
  --env "USE_MOCK_CLIENT=true" \
  -- docker run -i --rm \
    -e USE_MOCK_CLIENT \
    task-manager-mcp:latest
