Clipboard MCP Server runs on your own machine — the client starts it, so there is no endpoint to ping. 513 installs a week from npm. Last commit 29 Oct 2026.
Read, write, and inspect the system clipboard on macOS, Linux (X11/Wayland), and Windows via MCP.
Today is the operative word: we check Clipboard MCP Server every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Optional settings from the registry entry, left out of the block above:
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_LOG_LEVEL (Sets the minimum log level for output (e.g., 'debug', 'info', 'warn')), 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'), CLIPBOARD_READ_ONLY (Serve the clipboard read-only. When true, clipboard_write is absent from the manifest and tools/list and uncallable, but shown as disabled on the landing page and startup log. Accepts true/false/1/0/yes/no/on/off).
