MCP SERVERLook up how engineers actually say kubectl, nginx or JWT — IPA, a respelling, a playable MP3 and the citation.
LABSCO SUMMARY
The dictionary holds 1,883 entries and 1,263 of them carry a citable source — Wilhite on GIF, Crockford on JSON, RFC 7519 on JWT — with each entry tagged creator-clarified, community-consensus or contested, so a genuinely disputed reading comes back as disputed instead of as one arbitrary answer. Words outside the dictionary return an error, which is why the answers you do get are worth something.
A community-maintained pronunciation dictionary for developer project, product and jargon names, served over MCP. Ask for a word and you get how it is said, how the reading was settled, and audio you can play.
The server lives in the repository's mcp-server subdirectory and ships to PyPI as pronounce-mcp; the documented launch runs it with uvx straight from that subdirectory, and there is an OCI image at ghcr.io/anzy-renlab-ai/pronounce-mcp. Speaks stdio. It reads the public dictionary at pronounce.renlab.ai, so there is no account and no key. The CLI and editor extensions in the same repository are separate from the server.
One command — uvx pronounce-mcp
USE CASES
Look the word up and get the IPA, the respelling engineers actually use, and an MP3 you can play before standup.
The entry carries its confidence tag and, where one exists, the citation — a creator interview, a conference talk, an RFC.
Search by substring across the dictionary's words and categories, then read the match in full.
List entries filtered to cli-tool or acronym, with a limit so the result stays readable.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
list_pronunciationsList dictionary entries, optionally filtered by category.
Categories include: product, project, cli-tool, tool, cs-term, acronym, abbreviation, person. The dictionary holds well over 1500 entries and grows continuously, so the unfiltered list is large — pass category and/or limit to keep the result focused.
pronounceLook up the canonical pronunciation of a developer-related word.
Returns the IPA, a respelling that approximates how engineers actually say the word, a playable MP3 audio_url, optional alternate readings, the source citation when available, and editorial notes. Use this for project names like kubectl, nginx, GIF, JSON, Pydantic, Knative, programmer jargon, and tech acronyms. Returns an error dict if the word is not in the dictionary; for general English vocabulary, fall back to your own knowledge.
search_pronunciationsSearch the dictionary by partial word or category match.
Matches substrings against the entry's word and category only — the search index (/api/words.json) carries no notes or source text, so a query like "Kelsey" will NOT surface kubectl. To read an entry's notes, look it up with pronounce.
Returns a list of matching entries with word, slug, category, and confidence. Use this when the exact spelling is unknown or when browsing entries by category.
