Installing the mcp nextcloud calendar mcp server

The server is distributed via npm as The, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Configuration

Before the server will start you need to supply 3 environment variables: NEXTCLOUD_BASE_URL, NEXTCLOUD_USERNAME, NEXTCLOUD_APP_TOKEN. Keep credentials in your client's env block or a secrets manager rather than committing them.

Where it fits

Productivity servers pay off through capture: the tasks and notes that never get filed are the ones where opening the app is more friction than the thought is worth. MCP Nextcloud Calendar sits in that group, and the shape of its toolset — Installation — tells you what it is really for. Worth comparing against the other productivity servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • It will not start until its required credentials are present, so set those before wondering why the tools never appear.
  • Maintained by Cheffromspace, written in Go.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the mcp nextcloud calendar mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
