Instance Removal Strategies

The remove_instances tool provides a safe, intent-based interface for removing instances. Instead of remembering which API flags to set, you pick a strategy:

When confirm=false (default), the tool shows a detailed execution plan so you can review before proceeding:

remove_instances("o-abc123", "i-abc123", strategy="drain_and_replace")

→ SAFETY: Action NOT executed. Set confirm=true to proceed.
  DRAIN AND REPLACE 1 instance(s) in cluster o-abc123:
    Instances: ['i-abc123']
    Method: Rolling restart (20% per batch)
    - Pods will be gracefully drained (PDBs respected)
    - Instances will be terminated after drain
    - Ocean will automatically launch replacements

Setup

Environment Variables

export SPOTINST_TOKEN="your-spotinst-api-token"
export SPOTINST_ACCOUNT_ID="act-xxxxxxxx"

Install with pip

pip install mcp-server-spotinst

Install with uvx (no install needed)

uvx mcp-server-spotinst

Claude Code Config

Add to ~/.mcp.json:

{
  "mcpServers": {
    "spotinst": {
      "command": "uvx",
      "args": ["mcp-server-spotinst"],
      "env": {
        "SPOTINST_TOKEN": "your-token",
        "SPOTINST_ACCOUNT_ID": "act-xxxxxxxx"
      }
    }
  }
}

Docker

docker build -t mcp-server-spotinst .
docker run -e SPOTINST_TOKEN=your-token -e SPOTINST_ACCOUNT_ID=act-xxxxxxxx mcp-server-spotinst

Run Standalone

mcp-server-spotinst

Multi-Account Usage

Your personal API token can access multiple Spotinst accounts. Use list_accounts to see all available accounts, then pass account_id to any tool:

list_clusters(account_id="act-be5e7ffe")
get_cluster_nodes("o-390ef886", account_id="act-9785011e", cloud="azure")

Or use list_all_clusters for a single-call inventory across everything.
