The sample `mcpServers` entry in the README has `touch ~/Desktop/mcp_is_working.txt` as its command, which writes a file instead of starting the server. The name it hands to npx, `simple-time-mcp`, is not a package npm carries — that is the command the installed package provides. Point `command` at that binary and it connects. After that there is nothing to configure — one tool, one optional argument.
A single-purpose server that answers with the current date and time. It exists because a model has no clock of its own, and a wrong date quietly poisons anything scheduled, dated or compared.
- `get_time` returns the current date and time
- An optional `format` argument picks the shape: `full` for both (the default), `time` for the clock alone, `date` for the calendar day alone
The npm package @katomato65/time-mcp, version 1.0.3, which installs a `simple-time-mcp` command. The README's run line treats `simple-time-mcp` as a package name in its own right, which npm does not have; it is the command the installed package provides. No account, no key, no network access needed.
