One of the strange design decisions Anthropic made was depriving Claude of timestamps for messages sent by the user in claude.ai or current time in general. Poor Claude can't tell what time it is! mcp-simple-timeserver is a simple MCP server that fixes that. This server provides the following tools: All tools (except getlocaltime) use accurate time from NTP servers. If NTP is unavailable, they gra
