mistral-mcp

Mistral AI 기능을 모든 MCP 클라이언트(Claude Code, Cursor, Zed, Windsurf, Claude Desktop)에 노출하는 MCP 서버
프랑스어 버전: README.fr.md

version license node typescript mcp-spec tools resources prompts tests

목적

Mistral은 프랑스어, 코드, OCR, 조정, 오디오 및 에이전트 스타일 워크플로우를 위한 강력한 모델을 보유하고 있지만, 대부분의 MCP 지원 IDE는 Anthropic이나 OpenAI를 기본으로 사용합니다. mistral-mcp는 이러한 Mistral 기능을 깔끔한 MCP 인터페이스로 제공하여, 에이전트 루프를 다시 구축할 필요 없이 적절한 하위 작업을 적절한 모델로 라우팅할 수 있게 합니다.

이 저장소의 목표는 "또 하나의 얇은 래퍼"가 되는 것이 아닙니다. 명확한 스키마, 예측 가능한 출력, 전송 유연성 및 우수한 테스트 커버리지를 갖춘 강력하고 유지 관리 가능한 MCP 서버를 지향합니다.

codestral_fimCodestral fill-in-the-middle completionA

Read-only

Fill-in-the-middle code completion with Codestral.

Given prompt (code preceding the cursor) and suffix (code after the cursor), Codestral writes the middle. Use for editor autocomplete scenarios, code-patching agents, or structured refactors where you know the target boundaries.

Default stop tokens: [] — let the model decide. Override with stop if needed.

ParametersJSON Schema

Name	Required	Description
`seed`	No	Random seed for deterministic sampling. Maps to Mistral's `random_seed`.
`stop`	No	Stop generation when any of these text sequences is encountered.
`model`	No	FIM (fill-in-the-middle) model identifier. Any identifier your endpoint serves is accepted — read mistral://models for the live catalog. Known Mistral aliases: codestral-latest.
`top_p`	No	Nucleus sampling probability mass: 0.1 considers tokens in the top 10% of probability mass. Prefer adjusting this or temperature, not both.
`prompt`	Yes	Code preceding the cursor.
`suffix`	Yes	Code after the cursor. Can be empty string.
`max_tokens`	No	Maximum number of tokens to generate. Input tokens plus this limit must fit within the model's context length.
`temperature`	No	Sampling temperature: higher values make output more random; lower values make it more focused. Prefer adjusting this or top_p, not both.

A4.5/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=false, and destructiveHint=false. The description adds useful generation behavior by noting the default stop tokens are empty and that the model decides when to stop unless `stop` is overridden.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with a one-line purpose, followed by cursor semantics, use cases, and stop-token behavior. Every sentence earns its place and no filler is present.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given rich annotations, 100% schema coverage, and an output schema, the description supplies the missing conceptual model: prompt before cursor, suffix after cursor, and Codestral writes the middle. It is complete enough for correct invocation without redundant return-value explanation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so prompt/suffix meanings are already documented. The description adds extra semantics for `stop`: default is [] and the model decides, with explicit override guidance, going beyond the schema's brief stop description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: fill-in-the-middle code completion with Codestral, plus the prompt/suffix cursor model. The FIM and editor-autocomplete framing distinguishes it from sibling chat, vision, OCR, transcription, and document tools without needing schema inspection.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides clear usage contexts: editor autocomplete, code-patching agents, and structured refactors where target boundaries are known. It does not explicitly name when to avoid this tool or route to a sibling like mistral_chat for general generation.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

mistral_chatMistral chat completionA

Read-only

Generate a chat completion using a Mistral model.

When to use:

Drafting French (or any European-language) content where Mistral shines.
Codestral for code-specific generation/review.
Ministral for cheap / low-latency classification.

Returns structured content with the assistant text and token usage. Does NOT stream — use mistral_chat_stream for long outputs with progress updates.

ParametersJSON Schema

Name	Required	Description
`seed`	No	Random seed for deterministic sampling. Maps to Mistral's `random_seed`.
`model`	No	Chat model. Default: mistral-medium-latest (override with MISTRAL_DEFAULT_MODEL).
`top_p`	No	Nucleus sampling probability mass: 0.1 considers tokens in the top 10% of probability mass. Prefer adjusting this or temperature, not both.
`messages`	Yes	Chat messages in role/content form.
`max_tokens`	No	Maximum number of tokens to generate. Input tokens plus this limit must fit within the model's context length.
`temperature`	No	Sampling temperature: higher values make output more random; lower values make it more focused. Prefer adjusting this or top_p, not both.
`response_format`	No	Force a structured output: `{type:"json_object"}` for JSON mode, `{type:"json_schema", json_schema:{...}}` for strict schema mode.
`reasoning_effort`	No	Reasoning effort; supported values depend on the selected model.

Output Schema

ParametersJSON Schema

Name	Required	Description
`text`	Yes
`model`	Yes
`usage`	No
`finish_reason`	No
`reasoning_content`	No	Reasoning trace returned by Magistral models. Absent for non-reasoning models.

A4.4/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations cover safety (readOnlyHint=true, destructiveHint=false, openWorldHint=true), so the bar is lower. The description still adds useful non-safety behavior: it does not stream, and it returns structured content with assistant text and token usage. It does not mention rate limits, latency, or error behavior, keeping it short of 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.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loads the core action, organizes guidance as scannable bullets, and closes with the return shape and the streaming exclusion. No filler sentences.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, the description needn't detail return values, and annotations cover safety. It still supplies the streaming caveat and model-family guidance. Minor gap: it never states default model behavior or auth expectations, but that is largely handled by the schema's model description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents seed, model, top_p, temperature, response_format, and reasoning_effort thoroughly. The description adds only indirect model-selection guidance ('Codestral', 'Ministral') rather than explaining parameters, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The opening line states a specific verb and resource: 'Generate a chat completion using a Mistral model.' The bullets further differentiate sub-cases (French/European drafting, Codestral for code, Ministral for cheap classification), letting an agent distinguish this from codestral_fim and other siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicit 'When to use' bullets plus a named exclusion: 'Does NOT stream — use mistral_chat_stream for long outputs with progress updates.' This gives both positive triggers and a concrete alternative with the condition that selects it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

mistral_ocrMistral OCR (document to markdown)A

Read-onlyIdempotent

Run Mistral OCR on a PDF or image, returning structured markdown per page.

Input document is one of:

{ type: "document_url", documentUrl: "https://...pdf" }
{ type: "image_url", imageUrl: "https://..." | "data:image/..." }
{ type: "file", fileId: "" }

Options:

pages: array of 0-indexed page numbers or string like "0-5,7".
tableFormat: 'markdown' (default) or 'html'.
extractHeader / extractFooter: include page header/footer when present.
includeImageBase64: embed extracted image bytes as base64 in the response.
document_annotation_format: JSON schema for whole-document structured extraction.
bbox_annotation_format: JSON schema for extracted image / bbox annotations.
confidence_scores_granularity: 'page', 'word', or 'block'. 'block' adds per-block content/type confidence under pages[].blocks[].confidence_scores and requires OCR 4.1 or newer.
includeBlocks: return paragraph-level blocks (bounding box + type) in reading order — titles, lists, tables, images, equations, captions, code, references, aside text, header, footer, signature. Requires OCR 4 (mistral-ocr-4-0) or newer; older models accept the flag but return an empty blocks array.

Returns pages[].markdown plus optional pages[].hyperlinks, header, footer, images bounding boxes, blocks, annotations, confidence scores, and dimensions.

ParametersJSON Schema

Name	Required	Description
`model`	No	OCR model. Default: mistral-ocr-latest.
`pages`	No	Zero-based page numbers to process, as an array or comma-separated numbers and ranges such as "0-5,7".
`document`	Yes	Document to process, supplied as a document URL, an image URL or data URI, or an uploaded file ID.
`imageLimit`	No	Maximum number of images to extract from the document.
`tableFormat`	No	Format for extracted tables: Markdown or HTML.
`imageMinSize`	No	Minimum height and width of an image to extract.
`extractFooter`	No	Extract each page footer into its footer field and remove it from the page markdown.
`extractHeader`	No	Extract each page header into its header field and remove it from the page markdown.
`includeBlocks`	No	Return paragraph-level blocks (bounding box + type) per page. Requires OCR 4 (mistral-ocr-4-0) or newer.
`includeImageBase64`	No	Include base64-encoded data for extracted images in the response.
`bbox_annotation_format`	No	JSON Schema for structured annotations of each extracted bounding box or image.
`document_annotation_format`	No	JSON Schema for a structured annotation extracted from the entire document.
`document_annotation_prompt`	No	Instructions for whole-document structured extraction. Requires document_annotation_format.
`confidence_scores_granularity`	No	Confidence granularity. 'block' also fills pages[].blocks[].confidence_scores and requires OCR 4.1 (mistral-ocr-4-1) or newer.

A4.2/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the annotations (which only declare read-only, idempotent, non-destructive, open-world), the description discloses real behavioral preconditions: includeBlocks requires OCR 4+, confidence_scores_granularity='block' requires OCR 4.1+, and older models silently accept includeBlocks but return an empty blocks array. That silent-failure warning is exactly the kind of context an agent cannot get from the schema or annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with a one-line purpose, then cleanly sectioned into input shapes, options, and returns for a 14-parameter tool. The length is proportionate to the surface area and each bullet maps to a decision the caller must make.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only OCR tool with a full output schema and 100% schema coverage, the description supplies everything else needed: the three mutually exclusive document input forms, option semantics, model-version gates, and the shape of the response. Nothing an agent needs to invoke it correctly is absent.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

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 adds genuine value on several parameters the schema documents only tersely: the annotated string form of `pages` ('0-5,7'), the default of tableFormat, the distinction between document_annotation_format and bbox_annotation_format, and the version requirements tied to includeBlocks and confidence granularity. Some parameters (imageLimit, imageMinSize, model) are untouched, which keeps it from a 5.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb and resource ('Run Mistral OCR on a PDF or image') and states the core output ('returning structured markdown per page'). It is clear, but it never distinguishes itself from siblings like mistral_vision or process_document, so an agent cannot tell from the description alone which of those overlapping tools to pick.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the enumerated input shapes and option list, but there is no explicit when-to-use or when-not-to-use guidance, and no routing to alternative siblings such as mistral_vision for image-only OCR. The reader must infer the fit from the parameter list.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

mistral_visionMistral multimodal chat (vision)A

Read-only

Chat completion with multimodal input: text + image_url parts.

Requires a vision-capable model. Accepted:

pixtral-large-latest
pixtral-12b-latest
mistral-large-latest
mistral-medium-latest
mistral-small-latest

Each message's content is either a plain string (pure text) or an array of parts { type: 'text', text } / { type: 'image_url', imageUrl }. The image URL can be an https URL or a data: URI base64 payload.

Returns the assistant text + token usage. For non-visual requests, prefer mistral_chat.

ParametersJSON Schema

Name	Required	Description
`seed`	No	Random seed for deterministic sampling. Maps to Mistral's `random_seed`.
`model`	No	Vision-capable Mistral model. Default: pixtral-large-latest.
`top_p`	No	Nucleus sampling probability mass: 0.1 considers tokens in the top 10% of probability mass. Prefer adjusting this or temperature, not both.
`messages`	Yes	Chat messages. Pure-text requests are accepted, but this tool is intended primarily for multimodal prompts containing image parts.
`max_tokens`	No	Maximum number of tokens to generate. Input tokens plus this limit must fit within the model's context length.
`temperature`	No	Sampling temperature: higher values make output more random; lower values make it more focused. Prefer adjusting this or top_p, not both.

A4.6/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds useful non-structural context: the vision-model requirement, accepted model IDs, and that it returns assistant text plus token usage. It does not cover cost/latency or image size limits, so not a full 5.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the core purpose, then model list, then payload format, then routing guidance. The model enumeration is slightly verbose but each line is actionable and the structure is scannable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Output schema exists so return values needn't be explained, and the description still notes the assistant-text + token-usage return. Model constraints, payload shapes, and sibling routing are all present; nothing needed to call this correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3, but the description goes beyond by enumerating the accepted vision model IDs (the schema only says 'Vision-capable Mistral model') and clarifying the content part shapes and image URL formats.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource ('Chat completion with multimodal input: text + image_url parts') and explicitly differentiates from the sibling mistral_chat for non-visual requests. An agent can distinguish this from mistral_ocr and mistral_chat 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.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes usage: 'Requires a vision-capable model' with an enumerated accepted-model list, and states 'For non-visual requests, prefer mistral_chat.' This names both the condition to use it and the alternative to use otherwise.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

process_documentProcess a business document end-to-endA

Read-onlyIdempotent

Single-call pipeline: provided text/Markdown or Mistral OCR → classify (if kind=auto) → typed extraction → validation. source.type=text skips OCR and Files uploads. Text with kind=generic makes no API calls; classification and typed extraction use Mistral chat. Results expose extraction_source. Provided text has null ocr_confidence and page_count; ocr_text contains the supplied text unchanged. Replaces the manual chain of mistral_ocr + mistral_chat + JSON parsing.

Kinds: contract | invoice | id_document | generic. Use kind=auto to let the server classify. Returns a discriminated union — switch on kind to access typed fields. Validation checks schema and, for OCR sources, OCR confidence; not factual or accounting accuracy. Typed extraction rejects text longer than 60000 characters rather than truncating it.

Cache keys include source, kind, page limit, endpoint, models and pipeline version. Override location with MISTRAL_MCP_CACHE_DIR. Override mode with options.cache. Default cache mode is 'read_write' EXCEPT for kind=id_document (auto-bypass to avoid persisting PII). Set options.cache='read_write' explicitly to opt in for id documents.

options.maxPages and options.minOcrConfidence apply only to OCR sources. The confidence floor defaults to 0.3. Below the floor the tool returns isError. Missing or partial confidence scores also return isError; use mistral_ocr directly if you need raw OCR without a confidence guarantee. 0.3 is a conservative starting point, not a measured one: calibrate it for your corpus with npm run eval:docs.

ParametersJSON Schema

Name	Required	Description	Default
`kind`	No	Extraction task. auto classifies the document; generic returns text without typed extraction. Text source with generic makes no API calls.	auto
`source`	Yes	Already extracted text/Markdown, or an OCR source: remote URL, uploaded file ID, or inline image.

A4.8/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly/idempotent/non-destructive, but the description goes well beyond them: cache key composition and the id_document PII auto-bypass, the isError conditions around OCR confidence, that validation is schema-only (not factual), and the 60000-character rejection behavior. This is unusually rich behavioral disclosure for a read-only processing tool.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the pipeline summary, then grouped by concerns (sources, kinds, returns, validation, cache, options). Length is defensible for a 3-param nested pipeline tool, but a few statements restate schema facts (the 60000 limit, the 0.3 floor, maxPages/minOcrConfidence scoping), which is mild redundancy given a fully described schema.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, the description still usefully explains the discriminated-union return (switch on kind, extraction_source, ocr_confidence semantics). Combined with the caveats about confidence floors and cache bypass, an agent has everything needed to call and interpret the tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3, but the description adds framing the schema does not: that maxPages/minOcrConfidence apply only to OCR sources (and how they interact with provided text), that text sources yield null ocr_confidence/page_count, and that the 0.3 floor is a placeholder to calibrate. It adds value beyond the field-level docs, though several details (60000 chars, 0.3 default) are duplicated from the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a concrete pipeline with specific stages (classify → typed extraction → validation) and the input modalities it accepts. It also explicitly positions itself against siblings: 'Replaces the manual chain of mistral_ocr + mistral_chat + JSON parsing.' An agent can distinguish it from mistral_ocr and mistral_chat without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives explicit routing guidance: kind=auto lets the server classify, source.type=text skips OCR and Files uploads, text+generic makes no API calls, and 'use mistral_ocr directly if you need raw OCR without a confidence guarantee.' It names the alternative and the condition that selects it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

{ type: "file_url", fileUrl: "https://..." } (public URL)
{ type: "file", fileId: "" }

Options:

language: ISO-639-1 hint (e.g. 'fr', 'en'). Boosts accuracy when known.
temperature: sampling temperature.
diarize: return per-speaker segments (default false).
timestampGranularities: ['segment'] to return per-segment timestamps.
contextBias: list of phrases/terms that should bias the decoder.

Returns plain text, detected language, optional segments[], and token usage.

ParametersJSON Schema

Name	Required	Description
`audio`	Yes	Audio to transcribe, supplied as a public URL or an uploaded file ID.
`model`	No	STT model. Default: voxtral-mini-latest.
`diarize`	No	Identify speakers in the returned transcription segments. Defaults to false.
`language`	No	ISO-639-1 language hint (e.g. 'fr', 'en').
`contextBias`	No	Words or phrases to favor when decoding the audio.
`temperature`	No	Sampling temperature for transcription.
`timestampGranularities`	No	Only 'segment' is currently supported.

A4.4/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral context beyond that: accepted model IDs, default values for diarize and model, the only-supported granularity, and the shape of the response (text, language, segments, token usage). It does not mention auth or rate limits, but that is a minor gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the core action, then organizes models, source options, options, and return values into scannable bullet groups. It is efficient, though the option bullets partially duplicate what the schema already documents with 100% coverage.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema, full annotation coverage, and 100% schema description coverage, the description supplies everything an agent needs: models, input modes, option semantics, and defaults. No material gap remains for invoking this tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description nonetheless adds meaning beyond the schema by explaining intent ('language ... boosts accuracy when known', 'contextBias: phrases that should bias the decoder', 'diarize: return per-speaker segments'), which helps the agent use the parameters correctly.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The first sentence gives a specific verb and resource ('Transcribe an audio file to text'), which is unambiguous and clearly distinct from the sibling tools (chat, FIM, vision, OCR, document processing). An agent can immediately tell this is the audio speech-to-text tool 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.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly lays out the two mutually exclusive audio source modes (public URL vs. uploaded file ID) and when each applies, which is exactly the routing decision an agent must make. It does not name alternatives or exclusions for when *not* to transcribe, but the context is otherwise clear.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.1/5.0

Scored 2026-09-28 21:50 across 6 tools

Disambiguation4/5

Each tool targets a distinct modality/action: code FIM, text chat, OCR, vision chat, document pipeline, and audio transcription. There is minor overlap between mistral_chat and mistral_vision (both chat) and between process_document and mistral_ocr, but the descriptions explicitly steer selection, so confusion is limited.

Naming Consistency3/5

Names mix provider-prefixed conventions (codestral_fim, mistral_chat, mistral_ocr, mistral_vision, voxtral_transcribe) with a plain action name (process_document). The pattern is somewhat readable but not a predictable verb_noun scheme and the provider prefixes fragment consistency.

Tool Count4/5

Six tools is well-scoped for a multimodal Mistral wrapper, with each tool covering a distinct capability rather than redundancy. Slightly broad for a server named 'Document Extraction' since it also includes code completion and chat, but not excessive.

Completeness3/5

Covers OCR, vision, chat, transcription, and a combined pipeline, but several tools reference a Files API (fileId) that is not exposed as a tool, creating a dead-end for uploading files. No model-listing or file-management operations leave workflows partially blocked.
