## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `uvx` (confidence: high):

```json
"mcpServers": {
  "moltrust-mcp-server": {
    "command": "uvx",
    "args": ["moltrust-mcp-server"],
    "env": {
      "MOLTRUST_API_KEY": ""
    }
  }
}
```

**Requires environment variables:** `MOLTRUST_API_KEY` — the values above are empty placeholders; fill in real credentials before running (see the repository for what each one is for).
