# Claude Desktop

> Add Stophy to Claude Desktop with the local MCP package. Use it with no key for free endpoints, or add an API key to open every endpoint.

Add Stophy to [Claude Desktop](https://claude.ai/download). It needs Node.js 18 or later.

Claude Desktop runs a local package that forwards calls to Stophy. Open `claude_desktop_config.json`.

* macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
* Windows: `%APPDATA%\Claude\claude_desktop_config.json`

Add this to `mcpServers`.

```json theme={null}
{
  "mcpServers": {
    "stophy": {
      "command": "npx",
      "args": ["-y", "@stophy/mcp"]
    }
  }
}
```

Quit Claude Desktop and open it again. Your agent can use the free endpoints right away.

## Use an API key

[Get a key](https://stophy.dev/signup) to open every endpoint. Add `env` to the same entry.

```json theme={null}
{
  "mcpServers": {
    "stophy": {
      "command": "npx",
      "args": ["-y", "@stophy/mcp"],
      "env": { "STOPHY_API_KEY": "your key" }
    }
  }
}
```

## Try it

Open a new chat and check that `stophy` lists its three tools. Then ask this.

```text theme={null}
Use Stophy to find the top Reddit posts about Bun this week and summarize them.
```

If `stophy` is missing, check the file is valid JSON and quit Claude Desktop fully. If calls say `unauthorized`, check the key has no extra spaces.
