INI ↔ JSON conversion via @mukundakatta/ini-mcp — bidirectional parse/serialize

intentparse INI configuration files to JSON objects and serialize JSON back to INI format — sections, comments, quoted values, arrays, Unicode, round-tripconstraints
no-authcredential-freestdio transportnpm package

Verified recipe for @mukundakatta/ini-mcp v0.1.0. 2 tools: to_json ({text}) and to_ini ({value: object}). 20 calls, 100% success, p50=0ms. Handles sections, comments, quoted values, Unicode, arrays (items[]=syntax), empty values. Key gotchas documented.

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

Install & run: npm install @mukundakatta/ini-mcp → entry dist/server.js (stdio transport)

2 tools:

  • to_json ({text: string}) → {value: {...}} — parse INI text to JSON
  • to_ini ({value: object}) → raw INI text — serialize JSON to INI

20 calls, 100% success, p50=0ms (sub-millisecond after 4ms JIT on first call)

What works perfectly:

  • Sections → nested objects: [database]\nhost=localhost{database:{host:"localhost"}}
  • Comments stripped: both ; and # styles
  • Quoted values unquoted: "/var/lib/data" and '/var/log/app' → bare strings
  • Empty/blank values → empty strings (blank trimmed)
  • Special characters preserved: URLs with ?&, backslashes, @ in emails
  • Unicode safe: Turkish İ/ü, emoji 🌍
  • Whitespace around = trimmed correctly
  • No-value keys (bare verbose) → true
  • Duplicate keys: last wins (key=first\nkey=second\nkey=third"third")
  • Arrays: to_ini uses items[]=a\nitems[]=b PHP-style syntax
  • Boolean/number types preserved in to_ini output
  • Round-trip verified: parse→serialize→reparse = identical content

Key gotchas:

  1. ⚠️ `to_json` wraps result in `{value: ...}` — access .value to get the parsed INI
  2. ⚠️ Multiline backslash continuation NOT supporteddescription=this is a \\\nvery long treats \ as literal, splits into separate keys
  3. ⚠️ Dotted sections overwrite children[a.b.c]\nkey=deep then [a.b]\nkey=mida.b.c data LOST (later section recreates parent object)
  4. `null` → literal string "null" in to_ini (not omitted)
  5. `to_ini` returns raw INI text — not JSON (don't JSON.parse it)
  6. Empty INI{value: {}} (no error)
