概览

What is mcp-ephemeral-k8s?

A Python library for spawning ephemeral Model Context Protocol (MCP) servers on Kubernetes using Server-Sent Events (SSE). It supports multiple runtimes (Node.js via npx, Python via uvx) and works with mcp-proxy.

How to use mcp-ephemeral-k8s?

Run the server with uvx mcp-ephemeral-k8s or install as a Python package (pip install mcp-ephemeral-k8s and then mcp-ephemeral-k8s). Optionally deploy via a Helm chart. Connect using an SSE URL (e.g., http://localhost:8000/sse) with the sse transport.

Key features of mcp-ephemeral-k8s

  • Supports Node.js (via npx) and Python (via uvx) runtimes
  • Integrates with mcp-proxy for runtime execution
  • Works with local kubeconfig or in-cluster configuration
  • Can be run as an MCP server itself
  • Provides a Python library for programmatic session management
  • Exposes ephemeral MCP servers over SSE

Use cases of mcp-ephemeral-k8s

  • Spawning temporary MCP servers on Kubernetes for development or testing
  • Running MCP servers with different runtimes in isolated ephemeral pods
  • Automating MCP server lifecycle with a Kubernetes-based scheduler
  • Integrating MCP-based tools into CI/CD pipelines on Kubernetes

常见问题

1

What transport does the server use?

SSE (Server-Sent Events), as shown in the connection URL `http://localhost:8000/sse` and configuration example with `"transport": "sse"`.

2

Does it require a Kubernetes cluster?

Yes, it requires a Kubernetes cluster with valid `kubectl` configuration. A local cluster (e.g., Kind) can be used for development.

3

How can I connect to an ephemeral MCP server?

After spawning, the server provides an SSE URL. Configure your MCP client with that URL and transport set to `sse`.

4

What runtimes are supported?

Node.js (via `npx`) and Python (via `uvx`). The library works with `mcp-proxy` to run these runtimes.

5

What are the prerequisites?

Docker and a Kubernetes cluster (e.g., Kind or any cluster with `kubectl`). For installation via `uvx` or `pip`, Python is also required.
