Bareun (바른) — Korean NLP & Spell Checking
Server Details
Bareun (바른) is a Korean natural-language engine. This MCP server lets any MCP-compatible client hand Korean text to a dedicated Korean engine instead of guessing: analyze_syntax (morphological analysis with 47 POS tags and beta homograph sense disambiguation), analyze_syntax_raw (raw model output, no post-processing), tokenize, correct_grammar (spelling and spacing correction with per-edit blocks and rule categories), and list_pos_tags. Resources expose the POS tag table, server info, and the cu

Scored across 6 tools
The overlapping pair analyze_syntax / analyze_syntax_raw shares a name prefix, but the raw variant's description explicitly tells agents when to use the other one instead, so misselection risk is low. tokenize vs analyze_syntax and correct_grammar vs both are cleanly separated by their stated outputs (word boundaries vs morphemes vs correction blocks), and search_dict/list_pos_tags occupy distinct niches.
All six names use lowercase snake_case with a verb-initial pattern (analyze_*, correct_*, list_*, search_*, tokenize), which is predictable and readable. The only deviation is the bare verb 'tokenize' and the '_raw' qualifier, both of which read naturally within the same convention.
Six tools is well within a sensible range for a focused Korean NLP service, and each one maps to a distinct capability (morphology, raw morphology, spell check, tokenization, tag reference, dictionary pattern search). No tool looks like filler or a near-duplicate added just for volume.
The surface covers the core Korean NLP lifecycle: tokenize, analyze, correct, and look up tags/dictionary patterns. Minor gaps remain — there is no exact-word or lemma-based dictionary lookup (search_dict is jamo-pattern oriented), no document/batch-level operation, and no dedicated dictionary-entry detail tool, but agents can approximate these with the existing calls.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds that the output shape depends on format (compact gives a 'surface/POS' string; full gives the full JSON structure) and that with_sense is a beta WSD feature that returns sense numbers and definitions. This is useful context, but it says nothing about performance, limits, or errors. For a read-only analysis tool with annotations, a 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
It is four dense sentences, front-loaded with the core purpose and then the output formats and the beta option. Every sentence carries information; only the beta caveat adds mild noise.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
There are 8 parameters and no output schema, so the description must carry the return-value burden, and it partly does by describing both output formats and the sense payload. The remaining parameters are fully covered by schema descriptions, making this nearly complete for a read-only analysis tool.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so a baseline of 3 applies, but the description goes beyond the schema by giving a concrete disambiguation example for with_sense (배[腹]/배[船]/배[梨]) and by spelling out the compact-versus-full output contract. It does not explain encoding, auto_spacing, or auto_jointing, but those are fully documented in the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
It states a specific verb and resource: Korean morphological analysis that splits sentences into eojeol and morphemes and attaches POS tags. That distinguishes it from siblings like correct_grammar or search_dict, but it never contrasts with analyze_syntax_raw or tokenize, the closest alternatives.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It explains what each format and with_sense value produces, which implicitly guides parameter choice, but it gives no explicit statement of when to use this tool instead of analyze_syntax_raw or tokenize. Usage is only inferable from the described outputs.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds real behavioral context beyond that: which post-processing layers are deliberately suppressed, that output is the raw model inference, and that with_sense routes through a beta WSD path. It omits return-shape and any latency/size caveats, which keeps it below a 5.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Four compact sentences, front-loaded with the core differentiator (no post-processing) followed by the exclusion behaviour and then the alternative route. No filler, and the most decision-relevant clause comes first.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a read-only analysis tool with a fully documented schema and no output schema, the description covers purpose, suppression behaviour, and sibling routing adequately. The remaining gap is that the shape of the returned morpheme/tag structure is only sketched via the schema's format hints, not described.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so all five parameters are already documented in the schema, establishing a baseline of 3. The description only adds a marginal nuance for with_sense ('후처리 없이 함께 돌려줍니다') that the schema already conveys as WSD beta; format, encoding, and auto_split_sentence get no extra treatment in prose.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description states a specific verb and resource ('순수 형태소 분석 수행') plus a precise scope qualifier: no post-processing (compound decomposition, auto spacing, user dictionary). It also explicitly names the sibling it is not, analyze_syntax, so the agent can distinguish it without opening any schema.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
It gives an explicit when-to-use condition ('모델 성능 평가나 말뭉치 재태깅처럼 후처리가 섞이지 않은 출력이 필요할 때만') and an explicit alternative ('일반적인 분석에는 analyze_syntax 를 쓰세요'). Both the selecting condition and the routing target are stated.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint/openWorldHint, yet the description adds real behavioral detail: style and tone are preserved, output includes corrected sentence plus original/corrected blocks, and each fix carries a Hangul spelling rule clause with explanation and example. It omits the hate/discriminative-expression check block, which is a notable side output an agent would want to know about.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Four sentences, front-loaded with the core action and return shape, then distinguishing traits and the special ASR case. No filler, though the sentence about rule citations and the ASR sentence could be slightly tighter.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a 15-parameter, no-output-schema tool, the description supplies the missing return-value picture (corrected text, correction blocks, rule evidence) and notes style preservation. The numerous toggle flags are left entirely to the schema, which is acceptable given 100% coverage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% across all 15 parameters, so the schema carries the semantics. The description only loosely gestures at a few behaviors (spacing restoration, sentence boundary punctuation) without mapping them to the many enable_/disable_ flags, so baseline 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb and resource ('한국어 문장의 맞춤법·띄어쓰기를 교정합니다') and adds the distinctive trait that it only fixes erroneous spots rather than rewriting. It never names the sibling analysis tools, but its corrective role is naturally distinct from tokenize/analyze_syntax.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Gives clear usage context: suited to work where proofreading grounds must be presented, and explicitly covers the ASR/auto-caption case with no spacing at all. It does not state when to avoid the tool or point to a sibling alternative.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds useful context — that the output is JSON containing 47 entries with code/name/major/minor/enum fields — though it doesn't state that the result is static and parameter-free.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two tight sentences, front-loaded with what is returned, followed by the usage cue. No filler sentences.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
There is no output schema, but the description compensates by listing the exact fields returned, and the zero-param lookup nature is fully conveyed. Nothing an agent needs in order to call it is missing.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Zero parameters, so the baseline is 4 per the rubric. The description additionally enumerates the returned field set, which is return-value information rather than parameter semantics, so it doesn't push higher.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb+resource: returns the 47 POS tags used by 바른 형태소 분석, with the exact fields included. An agent can immediately distinguish this static lookup table from the analysis/generation siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly says to consult it when interpreting POS codes (NNG, JKS…) from analyze_syntax results, which ties it to the right sibling. It gives no explicit 'when not to use' or full alternatives list, keeping it short of a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
readOnlyHint/openWorldHint already establish the safety profile, and the description adds genuinely new cost information: an unindexed full scan of ~1M entries and the advice to probe scale with count_only. It also flags that with_definition inflates responses. Result ordering and truncation behavior are left unstated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Three front-loaded sentences: capability, concrete conditions/use cases, then the performance caveat. Dense but each sentence carries distinct information; no filler or repetition of the title.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With 8 parameters all schema-documented, annotations present, and no output schema, the description covers what an agent needs to call it correctly and avoid expensive broad queries. It stops short of describing the shape of returned entries (beyond the with_definition hint), which would help given the missing output schema.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% and the pattern grammar is thoroughly documented there, so the baseline applies. The description's mention of anchor=suffix with '-아지'/'둥이' largely restates what the anchor and pattern schema fields already say, adding little new parameter semantics.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb (검색) and resource (우리말샘 사전) plus the distinguishing mechanism — jaso/phoneme slot patterns that composed-form search cannot express. The concrete examples ('받침이 ㅎ인 용언', anchor=suffix endings like '-아지') make it unmistakable versus tokenize or analyze_syntax.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Gives concrete when-to-use scenarios — rhyme finding, 초성 quizzes, 끝말잇기, irregular-conjugation candidate collection — and a when-caution rule (broad patterns → check scale with count_only first). It does not explicitly say when to prefer a sibling such as tokenize for plain string splitting, so the routing is implied rather than complete.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds the meaningful behavioral detail that auto_spacing=true repairs mis-spaced input before splitting, but it says nothing about the return shape (tokens or offsets), which matters since no output schema exists.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Three short sentences, the splitting purpose is front-loaded, followed by the sibling routing and then the auto_spacing nuance. Nothing is redundant.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple read-only tokenizer the purpose and alternative routing are complete, but with no output schema the description never indicates what is returned (token list vs. offset tuples), which the encoding parameter implies is relevant. That gap keeps it at minimum-viable-plus.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, so the baseline is 3, but the description genuinely adds meaning: it explains that auto_spacing corrects incorrectly spaced sentences, beyond the schema's bare '자동 띄어쓰기를 적용한다'. The encoding parameter's effect on offsets is left to the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
States a specific verb and resource ('한국어 문장을 어절(토큰) 단위로 분리') and immediately contrasts it with the POS-producing sibling analyze_syntax. An agent can pick it apart from the other syntax tools without opening any schema.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicit when-to-use ('품사 정보 없이 어절 경계만 필요할 때') and names the concrete alternative for the opposite case ('형태소·품사가 필요하면 analyze_syntax'). No inference required.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
