mcp-server

Name: mcp-server
Availability: InStock
Author: Pulumi

The Pulumi MCP Server is a server implementing the Model Context Protocol (MCP) for interacting with the Pulumi CLI. It allows MCP clients to perform operations such as retrieving package information, previewing changes, deploying updates, and fetching stack outputs programmatically without needing the Pulumi CLI installed directly in the client environment. The server is currently under active development, and its API is experimental.
