Cross-Account & Cross-Cloud Management * List all accessible Spotinst accounts * List all Ocean clusters across all accounts and cloud providers (AWS + Azure) in a single call AWS Ocean Clusters * List/get details of AWS Ocean Kubernetes clusters, Virtual Node Groups (VNGs), and Elastigroups * Get allowed EC2 instance types and right-sizing resource suggestions Azure Ocean Clusters * List/get details of Azure Ocean clusters and Azure Virtual Node Groups Cluster Operations (AWS & Azure) * List nodes, get aggregated cost breakdowns by namespace or resource * List/get deployment rolls and scaling/activity log events Stateful Nodes * List and get details of AWS Managed Instances (Stateful Nodes) Scheduling & Health * Get scheduling and auto-scaler configuration * Composite health checks combining node status, recent errors, and active rolls Cost Analysis * Week-over-week (or custom period) cost trend comparisons * 30-day cost and savings summaries Tag Filtering & Config Export * Filter clusters and VNGs by tag key/value * Export cluster and VNG configurations as YAML for GitOps/backup Write / Destructive Operations (require confirm=true) * Remove instances using named strategies: drain_and_replace, replace, or remove_permanently * Initiate rolling restarts of cluster nodes (with batch size control) * Detach and optionally terminate instances from AWS Ocean clusters * Update AWS and Azure VNG configurations

Which integrations are available for this server?

Allows exporting Ocean cluster and Virtual Node Group (VNG) configurations in YAML format, supporting GitOps workflows and configuration backups.

How do I use Spotinst MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Spotinst MCP Server List all my Ocean clusters across all clouds and show their current status" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

`detach_instances`	Detach and optionally terminate instances from an AWS Ocean cluster
`update_vng`	Update an AWS VNG configuration
`update_vng_azure`	Update an Azure VNG configuration

All tools accept an optional account_id parameter to query any account.

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:

Strategy	What happens	Use case
`drain_and_replace`	Gracefully drain pods (respects PDBs), terminate, Ocean replaces. Default and safest.	Replacing a problematic node in production
`replace`	Immediately terminate, Ocean auto-replaces. No graceful drain. AWS only.	Fast replacement when drain isn't needed
`remove_permanently`	Terminate + reduce cluster capacity. No replacement. AWS only.	Downsizing the cluster

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.
