## MCP Setup

### Remote (Streamable HTTP) — Cursor, VS Code, most MCP clients

- URL: `https://mcp.leeway.tech/mcp`
- Header: `Authorization: Bearer YOUR_TOKEN`

### Claude Desktop (stdio bridge via mcp-remote)

Claude Desktop's "Add custom connector" UI only supports OAuth, which this API doesn't use. Bridge in via the `mcp-remote` npm package instead (runs via `npx`, no Leeway server to install):

```json
{
  "mcpServers": {
    "leeway": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.leeway.tech/mcp", "--header", "Authorization:Bearer YOUR_TOKEN"]
    }
  }
}
```
