Nothing serious here today

Today is the operative word: we check Slavonic every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

slavonic
slavonic_detransliterate
Find the real Church Slavonic word(s) whose scientific-Latin transliteration matches this input — the inverse direction of `slavonic_transliterate`. Because transliterate is lossy, this is a LOOKUP against the words already in the dictionary cache: attested spellings (normalized OCS Cyrillic) come back as source=dictionary. If none match, a single best-effort reconstruction is returned (source=reconstruction, approximate=true) — a guess in normalized OCS Cyrillic, not attested, with no Glagolitic or liturgical marks. Coverage grows as words are cached, so an identical query may return a reconstruction now and a dictionary hit later.
slavonic_get_inflections
Fetch the full declension (nominals) or conjugation (verbs) table for a lemma identified by a search result's inflection handle (entry_id + word_class). Use this only when a search ran without inline forms or left a match un-expanded — a default search already returns each match's table inline. Returns Markdown plus the table as structuredContent with the shape {"result": <paradigm>} per the declared outputSchema — switch on result.category ('nominal' | 'verbal' | 'not_found') before reading the body. Content from en.wiktionary.org (CC BY-SA 4.0).
slavonic_search
Look an Old Church Slavonic word up on Wiktionary and return its senses plus full declension/conjugation tables — attested content (singular, dual and plural), not invented. Any form of the word works; an inflected query is resolved to its lemma automatically via previously cached paradigms and the result notes the resolution. With search_language='eng' the query is an English word instead: the result lists its per-sense Old Church Slavonic equivalents (the translations block) plus their expanded entries. Returns Markdown plus the same result as structuredContent matching the declared outputSchema. Results are cached server-side; first-time queries reach the live upstream politely and calls are rate limited — on a rate-limit error, wait a few seconds and retry. Content is from en.wiktionary.org (CC BY-SA 4.0 — attribute and share alike if republished).
slavonic_transliterate
Render Church Slavonic — Cyrillic or Glagolitic — in the scientific Latin transliteration Wiktionary uses (богъ → bogŭ, ⰱⱁⰳⱏ → bogŭ). Liturgical reading marks (titlos, accents) are dropped and late Church Slavonic spellings folded, so copied liturgical text works as-is. Returns Markdown plus the transliterated output as structuredContent matching the declared outputSchema. Pure local transform: no dictionary lookup and no network.

Slavonic — questions

Answers built from our own checks of this server.

What can Slavonic do?
It exposes 4 tools, read directly from the server on our last check. Among them: slavonic_detransliterate, slavonic_get_inflections, slavonic_search, slavonic_transliterate. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Slavonic working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 191 ms. The bar chart above shows every period we have measured.
How do I connect Slavonic?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Slavonic need an API key?
No. Slavonic completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Slavonic?
It answers our handshake in 191 ms on average, which is faster than 73% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
