# Qwen Code MCP setup

> Configure Sendmux MCP in Qwen Code.

Use this page to connect Sendmux MCP to your AI client.

## Hosted OAuth

Use the hosted endpoint when the client supports remote MCP OAuth:

```text theme={null}
https://mcp.sendmux.ai/mcp
```

Add this to `.qwen/settings.json` for one project or `~/.qwen/settings.json` for all projects.

```json theme={null}
{
  "mcpServers": {
    "sendmux": {
      "httpUrl": "https://mcp.sendmux.ai/mcp",
      "trust": false
    }
  }
}
```

Use `/mcp auth` in Qwen Code if the server needs authentication.

## Local stdio

Install the local package once:

```bash theme={null}
pip install sendmux-mcp
```

Use a mailbox key for Mailbox or Sending:

```bash theme={null}
export SENDMUX_MBX_KEY=smx_mbx_...
```

Use a root key for Management:

```bash theme={null}
export SENDMUX_ROOT_KEY=smx_root_...
```

Add this to `.qwen/settings.json` or `~/.qwen/settings.json`.

```json theme={null}
{
  "mcpServers": {
    "sendmux-mailbox": {
      "command": "sendmux-mcp-mailbox",
      "env": {
        "SENDMUX_API_KEY": "$SENDMUX_MBX_KEY"
      },
      "trust": false
    }
  }
}
```

## Private HTTP

Start a local HTTP MCP server:

```bash theme={null}
SENDMUX_API_KEY=smx_mbx_... \
SENDMUX_MCP_HTTP_BEARER_TOKEN=local-mcp-token \
sendmux-mcp-mailbox --transport http --host 127.0.0.1 --port 8765
```

Use `http://127.0.0.1:8765/mcp` as the client URL.

```json theme={null}
{
  "mcpServers": {
    "sendmux-local": {
      "httpUrl": "http://127.0.0.1:8765/mcp",
      "headers": {
        "Authorization": "Bearer local-mcp-token"
      },
      "trust": false
    }
  }
}
```
