Overview

Endor provides ephemeral, isolated virtual machines to run services like MariaDB, PostgreSQL, Redis, and more locally without extra installation. Services start in seconds and expose only necessary ports, leaving no trace after exit. It supports MCP mode to enable AI agents and IDEs to launch and interact with these services securely. An optional full-networking mode allows running a complete Alpine Linux environment.

Use cases

  • Launch temporary database servers for development or testing
  • Integrate sandboxed services into AI agent workflows via MCP
  • Run key-value stores and message brokers locally without installation
  • Experiment with isolated Alpine Linux environments
  • Quickly spin up services for IDE extensions or automation scripts

Key features

  • Ephemeral isolated VMs for each service
  • Supports MariaDB, PostgreSQL, Redis, Memcached, RabbitMQ, Valkey, Alpine
  • Instant startup in under 5 seconds
  • MCP mode for AI agent and IDE integration
  • Full-networking mode for Alpine Linux sandbox
  • No persistent footprint after exit

From the project README

Endor

Endor provides instant, private, sandboxed environments for your favorite services anywhere Node is available. Run MariaDB, PostgreSQL and many more servers securely and in just a few seconds. Nothing extra to install, everything runs locally. Perfect for AI agents and humans in a hurry.

Each service will run in an ephemeral, isolated VM that only exposes the application ports. When you are done, you can exit Endor with CTRL+C and everything is gone without leaving a trace in your system.

MCP mode allows the services to be launched and used from AI tools like agents and IDEs. Your agents can now securely and safely launch database servers or KV stores as part of their capabilities!

An experimental full-networking mode can be optionally enabled, allowing you to run a fully-featured Alpine Linux machine.

Need a MariaDB database? Just type endor run mariadb. Claude Code wants to run a Valkey instance? Just run endor mcp.
