Configuration
| Variable | Required | Secret | Description |
|---|---|---|---|
| MCP_LOG_LEVEL | — | — | Sets the minimum log level for output (e.g., 'debug', 'info', 'warn'). |
| CLIPBOARD_READ_ONLY | — | — | Serve the clipboard read-only. When true, clipboard_write is not registered: it is absent from tools/list and uncallable, absent from the manifest but shown as disabled on the landing page and startup log. Accepts true/false/1/0/yes/no/on/off. |
| MCP_TRANSPORT_TYPE | — | — | Selects the HTTP transport. |
| MCP_HTTP_HOST | — | — | The hostname for the HTTP server. |
| MCP_HTTP_PORT | — | — | The port to run the HTTP server on. |
| MCP_HTTP_ENDPOINT_PATH | — | — | The endpoint path for the MCP server. |
| MCP_AUTH_MODE | — | — | Authentication mode to use: 'none', 'jwt', or 'oauth'. |
| MCP_HTTP_MAX_BODY_BYTES | — | — | Maximum inbound JSON-RPC request body in bytes. Defaults to 7 MiB so a full-size clipboard_write survives worst-case JSON escaping; 0 disables the guard. |
| MCP_SESSION_MODE | — | — | HTTP session mode: 'auto', 'stateful', or 'stateless'. 'auto' resolves to 'stateful'. This server defaults to 'stateless'. |
