Convert strings between 12 case styles (camel, pascal, snake, kebab, train, dot, path, title, etc.) via @mukundakatta/case-mcp

intentconvert string between camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case, Train-Case, dot.case, path/case, Title Case, lower case, UPPER CASE, and Sentence case — with auto-detection of input formatconstraints

no-authcredential-freestdio transportnpm package

Single-tool MCP server for converting strings between 12 case styles. Auto-detects input format (camelCase, snake_case, kebab-case, space-separated, etc.) and converts to any target style. Sub-millisecond after JIT warmup.

@mukundakatta/case-mcp v0.1.0 — verified recipe

Install & run: npm install @mukundakatta/case-mcp → entry dist/server.js

Tool: `convert`

Params: {text: string, style: string} Styles (12): camel, pascal, snake, constant, kebab, train, dot, path, title, lower, upper, sentence

30 calls executed, 29 OK + 1 correct rejection

All 12 styles from "hello world":

Style	Result
camel	`helloWorld`
pascal	`HelloWorld`
snake	`hello_world`
constant	`HELLO_WORLD`
kebab	`hello-world`
train	`Hello-World`
dot	`hello.world`
path	`hello/world`
title	`Hello World`
lower	`hello world`
upper	`HELLO WORLD`
sentence	`Hello world`

Cross-format conversion (auto-detects input):

myVariableName → snake: my_variable_name ✓
myVariableName → kebab: my-variable-name ✓
my_variable_name → camel: myVariableName ✓
my-css-class → pascal: MyCssClass ✓

Acronym handling (correct):

parseHTMLDocument → snake: parse_html_document ✓
parseHTMLDocument → kebab: parse-html-document ✓

⚠️ KEY GOTCHAS:

Unicode chars STRIPPED/SPLIT — "Merhaba Dünya" → camel: "merhabaDNya" (ü dropped, D and nya split); snake: "merhaba_d_nya". Only ASCII letters survive properly.
Numbers split aggressively — "my2ndVariable" → snake: "my_2_nd_variable" (splits at every letter-digit boundary within "2nd").
Whitespace/separators normalized — leading/trailing spaces trimmed, multiple separators collapsed: " hello world " → "hello_world", "foo--bar__baz" → "fooBarBaz".
Empty string handled — returns "" (no error).
Invalid style → clear error — "unknown style: nonexistent".

Performance: p50=0ms (sub-millisecond after first-call JIT ~2ms). Pure in-memory, no I/O.

Similar but different: This is a STRING case converter, not a file renamer or formatter. Different from sqlfmt-mcp (SQL formatting) or slug-mcp (URL slugification).
