The Pulumi MCP Server is a hosted Model Context Protocol server that connects AI coding agents to Pulumi Cloud and the Pulumi Registry. The setup guide covers Claude Code, Cursor, Claude Desktop, Windsurf and Kiro, along with other agents.
It is for engineers and infrastructure teams who already use Pulumi to define cloud resources in familiar programming languages and want their AI agents to work with that setup.
Setup happens in the agent you use. The guide has a section for each client. You authenticate either in the browser or with a token, and the guide includes a way to authenticate without a browser. Once connected, the agent can use the server's tools and prompts. The guide also includes example requests and troubleshooting notes.
The pricing page lists a Free plan at $0 for one user, with Pulumi-managed infrastructure, basic Pulumi ESC and up to 500 workflow minutes. Paid plans start at $40 per month for Essentials and $400 per month for Pro. Enterprise pricing is set by contract. The MCP server guide has a costs and edition requirements section that sets out which edition is needed.
Pulumi lets teams define, deploy and manage cloud infrastructure in TypeScript, JavaScript, Python, Go, .NET, Java, YAML or HCL. The site describes Pulumi as open source and free for individuals.
