Today marks a significant milestone in our evolution from Platform.sh to Upsun. We’re launching the Upsun MCP Server, a new integration that transforms how you interact with your favorite cloud application platform through AI assistants.
Available now in beta at https://mcp.upsun.com/mcp, this represents our commitment to bringing real AI improvements directly to your development workflow. As a beta release, we’re actively seeking feedback to shape its evolution and its features. Feel free to bring up issues or PR on the upsun-mcp-server GitHub repository.

​
Infrastructure management where you already work

The Upsun MCP server eliminates context switching entirely. Through integration with AI assistants like Claude, you manage your entire Upsun infrastructure using natural language, right where you’re already working. 
You: "Create a preview environment for my feature branch with PostgreSQL"
Claude: "I'll create that preview environment for you now..."
[Environment created with full production data clone in 2 minutes]
No terminal. No console. No documentation hunting. Your AI assistant becomes your infrastructure expert. MCP projects

​
Why MCP changes everything for infrastructure

​
Natural Language Infrastructure-as-Code

Traditional infrastructure management requires memorizing commands and syntax. With MCP, you describe what you want:
  • “Show me all active environments in my e-commerce project”
  • “Create a backup before I deploy this breaking change”
  • “Add Redis caching to my staging environment”
Your AI assistant translates intent into action, handling the complexity behind the scenes.

​
Seamless CI/CD integration

MCP servers aren’t isolated tools, they integrate directly into your existing workflows. Trigger deployments from your IDE. Monitor builds from your documentation. Manage resources from anywhere you interact with AI. This integration extends to your CI/CD pipelines.

​
Automation that thinks

Traditional automation follows rigid rules. AI-powered automation adapts. Need to scale resources based on complex patterns? Your AI assistant analyzes metrics, understands context, and makes intelligent decisions. Example scenarios MCP enables:
  • Intelligent resource allocation based on usage patterns
  • Automated troubleshooting with root cause analysis
  • Smart backup strategies that adapt to your workflow
  • Predictive scaling before traffic spikes

​
What you can do today

Every operation respects Upsun’s security model. The beta defaults to read-only operations for safety, with write operations available through explicit configuration.To enable write operations, add the "enable-write": "true" header to your MCP configuration. Only enable this if you understand the implications and trust your AI assistant with infrastructure modifications.
The Upsun MCP Server exposes our API through task oriented tools like the CLI does:

​
Project & Environment Management

  • Create and configure projects
  • Manage environments and deployments
  • Handle branching and merging strategies
  • Monitor activities and logs

​
Infrastructure Operations

  • Configure services and databases
  • Manage domains and SSL certificates
  • Create and restore backups
  • Set up routing and caching

​
Security & Access

  • Manage SSH keys
  • Configure access controls
  • Handle certificates

​
Part of our broader AI vision

The MCP server launch represents our broader commitment to AI-enhanced development. This is the first of many AI innovations coming to Upsun. We’re not adding AI as a gimmick. We’re solving real problems that cost you time and money. Every AI feature we ship must pass one test: Does it make developers’ lives genuinely better?

​
Upsun MCP Architecture

In order to ensure the best level of service and maintenance, Upsun has deployed its MCP with Streamable HTTP transport. It uses HTTP POST for client-to-server messages with optional Server-Sent Events for streaming capabilities. This transport enables remote server communication and supports standard HTTP authentication methods including bearer tokens, API keys, and custom headers.

​
Installation instructions

Set up the Upsun MCP Server in under a minute:
  1. Get your API token from the Upsun Console. Navigate to your account settings and generate a new API token with appropriate permissions for your projects.
  2. Configure your MCP client to connect to https://mcp.upsun.com/mcp
  3. Start managing infrastructure through natural language
