Google Patents MCP Server
Сервер Google Patents MCP ( google-patents-mcp )
Этот проект предоставляет сервер Model Context Protocol (MCP), который позволяет осуществлять поиск информации о патентах Google через API SerpApi Google Patents .
Установка через Smithery
Чтобы автоматически установить Google Patents MCP Server для Claude Desktop через Smithery :
npx -y @smithery/cli install @KunihiroS/google-patents-mcp --client claudeЖурнал изменений
v0.2.0 (2025-04-17)
Исправление: Реализованы пустые обработчики для методов MCP
resources/listиprompts/list.Исправление: Объявлена возможность
promptsпри инициализации сервера.Задача: Обновление зависимостей.
Эти изменения направлены на улучшение совместимости с клиентами MCP, такими как Claude Desktop, которым могут потребоваться эти стандартные конечные точки, хотя прямое тестирование с Claude Desktop еще не проводилось.

Функции
Предоставляет инструмент MCP
search_patentsдля поиска в Google Patents.Использует SerpApi в качестве бэкэнда.
Можно запустить напрямую с помощью
npxбез локальной установки.
Предпосылки
Node.js: рекомендуется версия 18 или выше.
npm: Требуется для запуска команды
npx.Ключ API SerpApi: для использования API Google Patents вам понадобится действительный ключ API от SerpApi .
Быстрый старт (с использованием npx)
Самый простой способ запустить этот сервер — использовать npx . Эта команда загружает (при необходимости) и запускает сервер напрямую.
npx @kunihiros/google-patents-mcpПримечание: замените @kunihiros/google-patents-mcp фактическим опубликованным именем пакета, если оно отличается.
Сервер запустится и будет прослушивать запросы MCP на стандартном вводе/выводе.
Конфигурация
Сервер требует ваш ключ API SerpApi. Вы можете предоставить его одним из следующих способов:
Переменная среды (рекомендуется для хостов MCP): Установите переменную среды
SERPAPI_API_KEYпри запуске сервера. Конфигурации хоста MCP часто позволяют устанавливать переменные среды для серверов.Пример фрагмента конфигурации хоста MCP (
config.jsonили аналогичный):{ "mcpServers": { "google-patents-mcp": { "command": "npx", "args": [ "-y", // Skips confirmation if the package isn't installed locally "@kunihiros/google-patents-mcp" // Use the correct package name ], "env": { "SERPAPI_API_KEY": "YOUR_ACTUAL_SERPAPI_KEY" // Optional: Set log level // "LOG_LEVEL": "debug" } } } }Файл .env: создайте файл
.envв каталоге, где вы запускаете командуnpx(для локального тестирования или если не используется хост MCP), или в вашем домашнем каталоге (~/.google-patents-mcp.env), со следующим содержимым:SERPAPI_API_KEY=YOUR_ACTUAL_SERPAPI_KEY # Optional: Set log level (e.g., debug, info, warn, error) # LOG_LEVEL=debugПримечание: Хотя использование файла
.envудобно для локального тестирования, для производства или интеграции с хостами MCP, установка переменной среды напрямую через конфигурацию хоста является рекомендуемым и более безопасным подходом. Основной предполагаемый вариант использования — выполнение черезnpx, где переменные среды обычно управляются вызывающим процессом или хостом MCP.
Сервер ищет файлы .env в следующем порядке: * ./.env (относительно того места, где запущен npx ) * ~/.google-patents-mcp.env (в вашем домашнем каталоге)

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but offers minimal behavioral insight. It mentions filtering and sorting but omits critical details like rate limits, authentication needs, pagination behavior, error handling, or response format. For a search tool with 13 parameters, this is insufficient.
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, efficient sentence that front-loads the core purpose and enumerates key capabilities without redundancy. Every word serves a purpose, making it highly concise and well-structured.
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 complex search tool with 13 parameters, no annotations, and no output schema, the description is incomplete. It lacks behavioral context, usage guidelines, and details on results or errors, leaving significant gaps for agent understanding.
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 the schema fully documents all 13 parameters. The description adds no additional parameter semantics beyond listing filter types, which are already covered in schema descriptions. Baseline 3 is appropriate as the schema does the heavy lifting.
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 action ('Searches Google Patents') and resource ('patents'), and mentions the service provider ('using SerpApi'). It lists key filtering capabilities, making the purpose specific and actionable. However, without sibling tools, it cannot differentiate from alternatives, preventing a perfect score.
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 no guidance on when to use this tool versus alternatives, prerequisites, or typical use cases. It lists filtering options but lacks context on optimal scenarios or limitations, leaving the agent without usage direction.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 1 tool
With only one tool, there is no possibility of ambiguity or confusion between tools. The single tool has a clear, distinct purpose focused on searching patents.
The single tool name 'search_patents' follows a consistent verb_noun pattern. Since there is only one tool, naming consistency is inherently perfect with no deviations to assess.
A single tool for a patents server feels thin and under-scoped. While search is a core function, the domain suggests potential for additional operations like retrieving patent details, analyzing trends, or filtering by categories, making the count too low for the apparent scope.
The tool surface is severely incomplete for a patents domain. It only provides search functionality, with obvious gaps such as retrieving full patent documents, getting metadata like citations or legal status, or managing saved searches, which limits agent workflows and causes dead ends.
