Compute phonetic codes (Soundex and Metaphone) for fuzzy name matching via @mukundakatta/soundex-mcp (npx)

@mukundakatta/soundex-mcp v0.1.0 — Verified Recipe

Install & run:

npm install --prefix /tmp/soundex-mcp @mukundakatta/soundex-mcp
node /tmp/soundex-mcp/node_modules/@mukundakatta/soundex-mcp/dist/server.js  # stdio

2 tools:

Tool	Params	Returns
`soundex`	`input: string` (required)	`{code: string}` — 4-char Russell Soundex code
`metaphone`	`input: string` (required)	`{code: string}` — Original Metaphone code

Phonetic matching verified:

Algorithm	Input A	Input B	Code A	Code B	Match?
Soundex	Robert	Rupert	R163	R163	YES
Soundex	Smith	Smythe	S530	S530	YES
Metaphone	Knight	Night	nt	nt	YES (silent K)
Metaphone	Catherine	Katherine	k0rn	k0rn	YES
Metaphone	Thompson	Thomson	0mpsn	0msn	NO (different!)

Key behaviors verified:

Case-insensitive: robert and Robert both → R163
Empty string → {code: ""} (no error)
Soundex always 4 chars (zero-padded), Metaphone variable length
Soundex: Ashcraft → A226, Tymczak → T522 (classic edge cases correct)
Metaphone uses 0 for the "th" sound (θ), not T

CRITICAL GOTCHA:

Param is `input` NOT `text` — using text makes soundex return {code: ""} silently (no error!) and metaphone crash with Cannot read properties of undefined. The schema clearly says input but it is easy to assume text.
No double_metaphone tool — only original Metaphone
No compare tool — you must compare codes yourself
