Moth
Moth — это легковесный MCP-сервер для анализа исправлений ошибок локально в проекте и хранения проверенных решений.
Что делает Moth
Moth получает вывод ошибок через MCP, скрывает потенциальные секретные данные, нормализует сбой, определяет вероятный стек, проверяет локальную память исправлений проекта и возвращает структурированную сводку по исправлению.
Moth не редактирует код, не выполняет команды оболочки, не сканирует репозитории, не требует бэкенда и не ведет глобальную базу данных ошибок.

Почему Moth?
Контекст исправления ошибок часто локален для проекта: команда, которая завершилась сбоем, используемый фреймворк, близлежащие конфигурации, а также исправления, которые уже сработали или не сработали в этом репозитории.
Moth делает этот рабочий процесс компактным и явным. Он анализирует предоставленный контекст ошибки, предлагает лучшее первое исправление и записывает только проверенные результаты исправлений в локальную память проекта.
Быстрый старт
Требуется Node.js 18+.
Запуск напрямую:
npx -y @stfade/moth moth-mcpИли глобальная установка:

Инструменты
Moth предоставляет ровно два MCP-инструмента.
analyze_error
Анализирует предоставленный вывод ошибки перед попыткой исправления.
Поля ввода:

Поля вывода:
analysis_idfingerprintstacklikely_causebest_first_fixverificationprior_project_fixesavoidconfidence
remember_fix_result
Записывает проверенную память исправлений локально в проекте.
Поля ввода:

Публичный ввод worked отклоняется. worked выводится из verification_result.
Жизненный цикл проверенной памяти
analyze_error
→ apply/attempt fix
→ run verification command
→ remember_fix_resultВызывайте remember_fix_result только тогда, когда:
исправление/изменение было действительно предпринято
команда проверки действительно была выполнена
результат четко «пройден» (
passed) или «не пройден» (failed)
Не вызывайте его для предложений, пропущенных изменений, отсутствия проверки, неоднозначных результатов или догадок.
Локальная память
Проверенная память исправлений локально в проекте хранится по адресу:
.moth/fix-memory.jsonlMoth хранит небольшой реестр анализа вне проекта, чтобы remember_fix_result мог сопоставить analysis_id с правильным путем к проекту после перезапуска MCP-сервера.
Навыки
Moth включает краткие навыки для совместимых агентов:
moth-debug-first-fixmoth-source-backed-researchmoth-verify-fix
Сам MCP-сервер не выполняет поиск в реальном времени в интернете. Совместимые агенты могут использовать свои собственные инструменты поиска, руководствуясь навыками Moth, когда требуются внешние источники.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states the output is 'deterministic' and 'project-local'. It does not disclose if the tool modifies state (e.g., reads files, changes anything), required permissions, or potential side effects, leaving agents to infer behaviors.
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?
The description is a single concise sentence that front-loads the core purpose. However, it sacrifices critical parameter and usage details, which is a minor structural flaw given the tool's complexity.
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?
Despite having a rich input schema and output schema, the description omits explanation of parameter roles, return format, and usage context. For a complex analysis tool, this is incomplete, though the output schema may partially mitigate return value clarity.
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?
The input schema has 6 parameters with 0% description coverage, yet the description adds no parameter information beyond mentioning 'error output' in the purpose. The other parameters (command, cwd, relevant_files, etc.) remain unexplained, forcing agents to guess their 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?
The description clearly states the tool analyzes error output and returns a deterministic project-local fix brief. It uses a specific verb ('analyze') and resource ('error output'), and the mention of 'fix brief' distinguishes it from the sibling tool 'remember_fix_result' which likely stores results.
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?
No guidance on when to use this tool versus the sibling 'remember_fix_result' or other alternatives. The description implicitly suggests using it when an error occurs, but does not specify prerequisites or exclude scenarios.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
remember_fix_resultRemember Fix ResultA
Record verified project-local fix memory only after a fix/change was actually attempted, the verification command was actually run, and the result is clearly passed or failed.

| stack | Yes | ||
| fix_attempted | Yes | ||
| verification_command | Yes | ||

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that the tool records memory only under specified conditions. However, it lacks details about side effects, authorization needs, or what happens if conditions are unmet. No annotations exist to supplement.
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?
The description is a single sentence, front-loaded with the verb and resource, and includes necessary conditional clauses. No redundant information.
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?
Given the tool has 7 required parameters and no annotations, the description is insufficient. It does not explain what 'fix memory' is, how to obtain analysis_id/fingerprint/stack, or what the output schema contains. An agent would struggle to use this tool correctly.
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?
The schema has 7 parameters with 0% description coverage. The description does not explain any parameters, forcing agents to infer meaning from names alone. This is a significant gap given the tool's complexity.
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 clearly states the tool's purpose: to record a verified fix result after a fix attempt and verification. It specifies the exact conditions (fix attempted, verification run, result passed/failed) and distinguishes from analyze_error.
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?
The description provides clear context for when to use: only after a fix is attempted and verification run with a clear result. It does not explicitly state when not to use or mention alternatives, but the conditions are well-defined.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Tool Schema Changelog

v0.1.0- First observed
analyze_error - First observed
remember_fix_result
TDQS
The two tools have clearly distinct purposes: analyze_error generates a fix brief from error output, while remember_fix_result records the outcome of a fix attempt. There is no overlap or ambiguity.
Both tool names follow a consistent verb_noun pattern in snake_case: analyze_error and remember_fix_result. The naming is clear and predictable.
With only 2 tools, the server feels under-scoped for a typical error analysis workflow. While it may be intentionally minimal, a more comprehensive set would include tools for retrieving fix history or clearing memory.
The tool set lacks retrieval capabilities (e.g., listing or searching past fix results) and memory management (e.g., clearing or updating records). These are notable gaps that could hinder agent workflows.
