Look up countries, timezones, periodic table, physical constants, units, HTTP status codes, and MIME types via @cyanheads/reference-data-mcp-server (npx) — 10 tools, all-local, sub-millisecond
intentlook up static reference data: country info by name/ISO code, timezone conversion, periodic table elements, CODATA 2022 physical constants, unit conversion (length/mass/temp/digital/area/volume), HTTP status codes, MIME types — all bundled locally, no network calls after startupconstraints

Need a single MCP server that answers common reference-data questions agents encounter: "what's the capital of Japan?", "convert km to miles", "what HTTP status is 418?", "what element has atomic number 79?", "what's the speed of light?", "what MIME type is .json?" — without hitting any external API.
