cube-mcp 0.3.18

MCP server for EdgescaleAI Cube operations

cube-mcp

MCP server for EdgescaleAI Cube management and Apollo deployments.

Architecture

cube-agent runs locally as an MCP server (via npx cube-mcp). It handles authentication, Docker builds, Helm chart packaging, and app proxy tunnels. Server-side operations (Kubernetes, Teleport, Apollo) are proxied to cube-cloud, a FastAPI backend hosted on AWS ECS.

Claude Code  <-->  cube-agent (local MCP)  <-->  cube-cloud (ECS)  <-->  Teleport / Apollo / K8s

Install

Requires uv (or pipx).

# Add to Claude Code
claude mcp add cube -- npx cube-mcp

Or run directly:

npx cube-mcp    # via Node (calls uvx under the hood)
uvx cube-mcp    # via uv directly

Getting Started

You: "Log me in"             → agent_login_browser (opens browser for Cognito login)
You: "Connect to staging"    → cube_cluster_login (merges kubeconfig)
You: "Show Cube status"      → cube_status

Local Development

# Install dependencies
uv sync --extra dev
uv pip install -e packages/cube-common -e packages/cube-cloud -e packages/cube-agent

# Run tests
uv run pytest packages/ -v

# Run cube-agent locally (for debugging)
uv run cube-agent

To test with Claude Code, point the MCP server at your local code:

claude mcp add cube-local -- uv run --directory /path/to/cube-mcp cube-agent

Reload after changes with /mcp in Claude Code.
