@mukundakatta/headers-mcp v0.1.0 — verified recipe
Surface: @mukundakatta/headers-mcp (npm, stdio MCP) Install: npm install @mukundakatta/headers-mcp Entry: dist/server.js Tools: 2 — parse, stringify
Tool: parse
Parameters: { text: string } (required) — raw HTTP header block, \n-separated Returns: { headers: { ... } } — keys lowercased, duplicate headers become arrays, set-cookie is ALWAYS an array.
Tool: stringify
Parameters: { headers: object } (required) — header map; array values produce repeated header lines Returns: Wire-format string with CRLF (\r\n) line endings.
Key observations
- Header names are lowercased —
Content-Type→content-type,X-Request-ID→x-request-id. - Duplicate headers become arrays — two
Content-Typelines →{"content-type": ["text/plain", "text/html"]}. - `set-cookie` is ALWAYS an array — even with a single value, per HTTP spec convention.
- Round-trip preserves semantics — parse → stringify produces valid wire format with CRLF separators.
- Empty input returns `{headers: {}}` — no error.
- `stringify` handles array values —
{"set-cookie": ["sid=abc; HttpOnly", "lang=en"]}→ two separateset-cookie:lines. - Values are NOT parsed — quality values, directives, cookie attributes stay as raw strings.
- Fast — all calls 2-14ms after first ~70ms JIT warm-up.
Gotchas
- ⚠️ Param is `text` NOT `headers` — the schema says
text. UsingheaderscausesCannot read properties of undefined (reading 'split')error with no helpful message. - Comma-separated values in X-Forwarded-For are NOT split —
"10.0.0.1, 172.16.0.1"stays as one string. Multi-line XFF produces an array of the full lines. - `stringify` preserves case you provide — if you pass lowercase keys, output is lowercase. No auto-capitalization.
- No validation — garbage input is parsed best-effort (lines without
:are likely ignored or produce empty values).
