# Pulumi MCP server

> Query Pulumi Cloud stacks and resources, search the Pulumi Registry and delegate infrastructure tasks to Pulumi Neo.

- Listing: https://mcp.tc/i/pulumi
- Connect: use the server's own URL `https://mcp.ai.pulumi.com/mcp` (OAuth sign-in at the server); clients connect to it directly. The listing link is a page, not an MCP endpoint.
- Type: remote (Streamable HTTP)
- Auth: OAuth sign-in
- Category: [Cloud & DevOps](https://mcp.tc/c/cloud-devops)
- Vendor: Pulumi
- Verified: yes, mcp.tc checked that this is the official server (https://mcp.tc/verify). It says who runs the server, not that it is safe.

## About

Connects an AI assistant to Pulumi Cloud. It can look up stacks and resources in your organization, search the Pulumi Registry for providers and packages, and hand infrastructure tasks to Pulumi Neo, Pulumi's AI infrastructure agent.

The server is hosted by Pulumi at mcp.ai.pulumi.com and uses streamable HTTP. Access is through OAuth: during sign-in you paste a Pulumi access token and choose an organization. The requested scopes cover read and write access. No local install is needed.

## What it can do

- Query Pulumi Cloud stacks and their resources
- Search the Pulumi Registry for providers and packages
- Delegate infrastructure tasks to Pulumi Neo
- Use Pulumi Cloud from assistants such as Cursor, Claude Code and Windsurf

## Example prompts

- "List the stacks in my Pulumi organization"
- "Search the Pulumi Registry for an AWS S3 bucket resource"
- "Show the resources in my production stack"
- "Ask Neo to update my staging stack to use a larger instance size"

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http pulumi https://mcp.ai.pulumi.com/mcp
```

2. Start Claude Code, type `/mcp`, pick **pulumi** and choose **Authenticate**. A browser window opens for the Pulumi sign-in.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Settings → Connectors** and click **Add custom connector**.

2. Name it **Pulumi** and paste this URL:

```url
https://mcp.ai.pulumi.com/mcp
```

3. Click **Add**, then **Connect**, and sign in when Pulumi asks.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Pulumi&connectorUrl=https%3A%2F%2Fmcp.ai.pulumi.com%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://mcp.ai.pulumi.com/mcp` and click **Add**.

3. Click **Connect** and sign in when Pulumi asks.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, open **Settings → Security and login** and turn on **Developer mode**.

2. Go to `chatgpt.com/plugins` and click **+** to create an app for a remote MCP server.

3. Paste `https://mcp.ai.pulumi.com/mcp` as the server URL and choose **OAuth**. ChatGPT sends you to Pulumi to sign in.

Developer mode is available on the web for Plus, Pro, Business, Enterprise and Education accounts.

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=pulumi&config=eyJ1cmwiOiJodHRwczovL21jcC5haS5wdWx1bWkuY29tL21jcCJ9>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "pulumi": {
      "url": "https://mcp.ai.pulumi.com/mcp"
    }
  }
}
```

Cursor shows **Needs login** next to the server. Click it to sign in.

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=pulumi&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fmcp.ai.pulumi.com%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"pulumi","type":"http","url":"https://mcp.ai.pulumi.com/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "pulumi": {
      "type": "http",
      "url": "https://mcp.ai.pulumi.com/mcp"
    }
  }
}
```

VS Code asks you to sign in the first time the server starts.

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "pulumi": {
      "serverUrl": "https://mcp.ai.pulumi.com/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade and sign in when asked.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add pulumi --url https://mcp.ai.pulumi.com/mcp
codex mcp login pulumi
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.pulumi]
url = "https://mcp.ai.pulumi.com/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http pulumi https://mcp.ai.pulumi.com/mcp
```

Then, inside Gemini CLI, run `/mcp auth pulumi` to sign in.

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "pulumi": {
      "type": "http",
      "url": "https://mcp.ai.pulumi.com/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://mcp.ai.pulumi.com/mcp`.
