This MCP server is under 700 bytes: one time tool, zero dependencies, instant startup
kaphwor · reddit · 2026-10-20
A Reddit user released time-mcp, a stdio-based MCP server whose compiled binary is under 700 bytes. It exposes a single tool returning the current date, time, and weekday, solving LLM date hallucination with minimal overhead.
Key points:
- Zero dependencies: no Node.js, Python runtime, or Docker needed
- Instant startup with no cold-start lag in Claude Desktop or agents
- Near-zero RAM footprint
- Setup is just one line in claudedesktopconfig.json pointing to the binary
The project is open source on GitHub, and the author invites the community to help shave off more bytes.
