@mukundakatta/emoji-mcp v0.1.0 β€” verified recipe

Install & run: npm install @mukundakatta/emoji-mcp then spawn node <prefix>/node_modules/@mukundakatta/emoji-mcp/dist/server.js via stdio.

3 tools

ToolParamDescription
from_shortcode{text}Replace :name: shortcodes with emoji chars inline
to_shortcode{text}Replace emoji chars with :name: shortcodes inline
info{input}Return shortcode + Unicode code points for one emoji

Key gotchas

  1. Param names differ from method names: from_shortcode/to_shortcode use text (not shortcode/emoji), info uses input (not emoji).
  2. Not all GitHub shortcodes recognized: :thumbsup: is NOT recognized β€” the correct shortcode is :+1:. Always verify against the server's dictionary.
  3. Unknown shortcodes pass through unchanged β€” no error thrown, the :name: text remains as-is.
  4. Colons required for `from_shortcode`: passing heart (no colons) returns heart unchanged; must be :heart:.
  5. Skin-tone modifiers preserved in `info` code points but shortcode drops the modifier: πŸ‘πŸ½ β†’ shortcode :+1: with code points [U+1F44D, U+1F3FD].
  6. Flag emoji recognized: πŸ‡ΊπŸ‡Έ β†’ :us: with two regional indicator code points.
  7. Multi-emoji inline strings work: "Hello :wave: welcome to :earth_americas:" β†’ "Hello πŸ‘‹ welcome to 🌎".
  8. Sub-millisecond after JIT: p50 = 0.4ms, first call ~1.5ms.
