Let AI agents work in isolated microVMs.

Connect the hosted Nodion MCP server with a personal API key and your agent gets tools to create sandboxes, run commands, edit files and open previews.

# in Claude Code, with Nodion connected over MCP
> create a sandbox, clone acme/shop and run the tests
  sandboxes.create            checkout-fix, GP-G2-4GB, agents image
  sandboxes.exec              git clone https://github.com/acme/shop
  sandboxes.exec              npm ci && npm test
  42 passed

> start the app and give me a link
  sandboxes.exec              nohup npm run dev -- --port 3000 &
  sandboxes.previews.create   port 3000

Setup for Claude Code and Cursor is on the coding agents page.

The nodion CLI covers the whole lifecycle, from create to delete.

# create a sandbox with the coding agents image and your Anthropic key
nodion sandboxes create --name checkout-fix --region REGION \
  --package-sku compute.session.gp-g2-4gb --image agents \
  --secret-env ANTHROPIC_API_KEY=sk-ant-…

# run a command
nodion sandboxes exec SANDBOX_ID --cmd "cd /workspace && git clone https://github.com/acme/shop"

# write a file into the workspace
nodion sandboxes fs SANDBOX_ID --action write --path notes.md --content "hello"

# share port 3000 as an HTTPS URL
nodion sandboxes previews create SANDBOX_ID --port 3000

Install and sign in as described in the CLI docs.

Every sandbox endpoint lives under https://api.nodion.com/v2/sandboxes and takes a bearer token.

# create a sandbox
curl -X POST https://api.nodion.com/v2/sandboxes \
  -H "Authorization: Bearer $NODION_TOKEN" \
  -H "X-Nodion-Project: $NODION_PROJECT" \
  -H "Content-Type: application/json" \
  -d '{"name": "checkout-fix", "region_id": "REGION", "package_sku": "compute.session.gp-g2-4gb", "image": "agents"}'

# run a command, up to 15 minutes
curl -X POST https://api.nodion.com/v2/sandboxes/$SANDBOX_ID/exec \
  -H "Authorization: Bearer $NODION_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"cmd": ["npm", "test"], "dir": "/workspace/shop", "timeout_sec": 300}'

Files, logs, power, previews and environment variables have their own endpoints next to exec.
