Estonian NLP tools so AI agents stop hallucinating Estonian. 28 read-only tools wrapping EstNLTK, EKI Reeglid, and Riigi Teataja: spell-check, morphological analysis, lemmatization, full inflection paradigms, WordNet synonyms, fastText related words, named-entity recognition, orthography/grammar checks (capitalization, compounds, commas, numbers, abbreviation hyphenation, object case, register, style, redundancy, calque risk), compound attestation and an organisation’s own domain glossary, editorial checks that catch kantseliit in reports and academic prose, flag a document that names one thing three ways and spot Estonian that keeps English sentence structure, plus legal-Estonian tools (legalese simplification that protects terms of art, defined-term + cross-reference tracking, and canonical legal-usage collocations from public-domain legislation). Paradigms cover ordinals, comparatives, superlatives and proper nouns, include the short illative (majja beside majasse), and lead every slot with the form built on that paradigm’s own stem, so raamatutele comes before the literary raamatuile. A word with two inflection types (kott inflects as either koti or kota, two different words sharing a nominative) returns one consistent table per type instead of a merged one. Results are lean: one compact block per call, no echoed input, about half the tokens of earlier versions. Offline and PII-free: no third-party calls and nothing stored, and self-hosted, confidential text never leaves the machine. Works in Claude, ChatGPT and Codex, and is listed in Anthropic’s official Connectors Directory. Scores 99.1% on TalTech’s inflection_et and 100% once the 13 gold rows that contradict EKI are adjudicated, plus 99.3% first-form over all fourteen cases on 11,011 rows of real Estonian text. Use it as ground truth so the model stops inventing Estonian spelling and case forms and stops guessing whether a word fits its register or its domain.

MCP readiness

B · 88/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here B, 75.5/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ

Valid MCP handshake	10/10	initialize and tools/list both answered.
Live MCP endpoint	25/25	Endpoint answers the MCP initialize handshake (1643 ms).
Protocol revision	8/10	Speaks MCP 2025-11-25, 1 revision(s) behind 2026-07-28.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	15/15	31/31 probes succeeded over 30 days (100%).
Tool declaration	10/10	Lists 28 tool(s) with descriptions.
Verified identity	5/10	Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Auth declaration	2/5	Declares credential scheme: smithery_api_key.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Responsive (1643 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 53,039 reachable MCP servers in our daily snapshot (2026-11-12 06:46 UTC). Display only; it does not change search order.

Readiness: Higher than 95% of peers; This listing 88 · peer median 81
Latency: Faster than 34% of peers; This listing 465 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Verified identity −5 — Claim the listing and prove control of its domain.
Now: Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Auth declaration −3 — State how to authenticate (an auth scheme, or that none is needed).
Now: Declares credential scheme: smithery_api_key.
Protocol revision −2 — Support the current protocol revision.
Now: Speaks MCP 2025-11-25, 1 revision(s) behind 2026-07-28.
