用法

该服务器提供了一个名为get_stories的工具,可用于从 Hacker News 获取故事。

工具:get_stories

参数:

  • type (字符串):要获取的故事类型

    • 选项:‘顶部’、‘新’、‘询问’、‘显示’、‘工作’

    • 默认值:10

使用示例:

use_mcp_tool with:
server_name: "hacker-news"
tool_name: "get_stories"
arguments: {
  "type": "top",
  "limit": 5

[
  {
    "title": "Example Story Title",
    "url": "https://example.com/story",
    "points": 100,
    "author": "username",
    "time": "2024-12-28T00:03:05",
    "commentCount": 50,
    "rank": 1
  },
  // ... more stories
]

与克劳德整合

要将此 MCP 服务器与 Claude 一起使用,您需要:

  1. 已安装 Claude 桌面应用程序或 VSCode Claude 扩展

  2. 在您的设置中配置 MCP 服务器

  3. 使用 Claude 的自然语言界面与 Hacker News 进行交互

配置

对于 Claude 桌面应用程序,将服务器配置添加到:

// ~/Library/Application Support/Claude/claude_desktop_config.json (macOS)
// %APPDATA%\Claude\claude_desktop_config.json (Windows)
{
  "mcpServers": {
    "hacker-news": {
      "command": "node",
      "args": ["/path/to/hn-server/build/index.js"]
    }
  }
}

对于 VSCode Claude 扩展,添加:

// VSCode Settings JSON
{
  "mcpServers": {
    "hacker-news": {
      "command": "node",
      "args": ["/path/to/hn-server/build/index.js"]
    }
  }
}

交互示例

配置完成后,您可以使用自然语言与 Claude 互动,获取 Hacker News 报道。示例:

  • “向我展示 Hacker News 的五大新闻”

  • “Ask HN 的最新帖子是什么?”

  • “获取今天最热门的 Show HN 提交内容”

Claude 会自动使用适当的参数来获取您想要的故事。

TDQS

C2.9/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Get stories' implies a read operation, but the description doesn't mention rate limits, authentication requirements, pagination behavior, or what format the stories are returned in. For a tool with no annotation coverage, this leaves the agent with insufficient information about how the tool behaves in practice.

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?

The description is extremely concise - just four words that directly state the tool's purpose. Every word earns its place, and there's no wasted language. The structure is front-loaded with the essential information, making it immediately clear what the tool does.

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

Completeness2/5

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

Given that there's no output schema and no annotations, the description should provide more context about what the tool returns and how it behaves. 'Get stories from Hacker News' doesn't indicate whether this fetches current stories, historical data, or what fields are included in the response. For a tool with rich parameter options but no output documentation, the description is insufficiently complete.

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?

The input schema has 100% description coverage, with both parameters ('limit' and 'type') fully documented in the schema itself. The description adds no additional parameter information beyond what's already in the structured schema. According to the scoring rules, when schema_description_coverage is high (>80%), the baseline is 3 even with no param info in the description.

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 clearly states the verb ('Get') and resource ('stories from Hacker News'), making the purpose immediately understandable. It lacks sibling differentiation, but since there are no sibling tools on this server, that's not a deficiency. The description is specific enough to distinguish this from other potential tools like 'get_comments' or 'search_stories'.

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

Usage Guidelines2/5

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. It doesn't mention prerequisites, timing considerations, or contextual factors that would help an agent decide when this is the appropriate tool. With no sibling tools, the absence of differentiation isn't problematic, but the complete lack of usage context is a significant gap.

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

Disambiguation5/5

With only one tool, there is no possibility of ambiguity or overlap between tools. The single tool 'get_stories' has a clearly distinct and singular purpose.

Naming Consistency5/5

The naming is trivially consistent as there is only one tool. The tool name 'get_stories' follows a clear verb_noun pattern, which would be consistent if more tools were added.

Tool Count2/5

A single tool is too few for a server named 'Hacker News MCP', which implies broader functionality. While 'get_stories' is a core operation, the server lacks tools for other common actions like getting comments, user profiles, or posting, making it feel thin and incomplete.

Completeness1/5

The tool surface is severely incomplete for a Hacker News API. It only provides 'get_stories', missing essential operations such as retrieving comments, user details, search functionality, or any write operations, which are typical for such a domain.
