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).

Clipboard MCP Server — questions

Answers built from our own checks of this server.

Why is there no uptime for Clipboard MCP Server?
Clipboard MCP Server runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @cyanheads/clipboard-mcp-server was installed 513 times last week.
How do I connect Clipboard MCP Server?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @cyanheads/clipboard-mcp-server straight from npm; nothing to host, nothing to sign up for.
How many people use Clipboard MCP Server?
The npm package @cyanheads/clipboard-mcp-server was installed 513 times in the last week. Week over week that is +317%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Clipboard MCP Server open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 3 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
