Buienradar MCP Server
ブイエンレーダーMCPサーバー
概要
これは、Buienradarを使用して、指定された緯度と経度の降水量データを取得するMCPサーバーです。このサーバーは、今後2時間の降水量予測を提供する単一のMCPツールget_precipitation_forを公開しています。
Smithery経由でインストール
Smithery経由で Claude Desktop 用の Buienradar MCP Server を自動的にインストールするには:
npx -y @smithery/cli install @wpnbos/buienradar-mcp-server --client claudeRelated MCP server: Buienradar MCP Server
構成
まず、 uv (および Python) がインストールされていることを確認します。
このサーバーをClaude for Desktopと統合するには、次の場所にある構成ファイルを更新します。
MacOS/Linux
~/Library/Application Support/Claude/claude_desktop_config.jsonウィンドウズ
code $env:AppData\Claude\claude_desktop_config.json構成例:
{
"mcpServers": {
"precipitation": {
"command": "uv",
"args": [
"--directory",

"run",
"server.py"
]
}
}
}/ABSOLUTE/PATH/TO/PARENT/FOLDER/buienradar-mcp-serverサーバーが配置されている実際のパスに置き換えます。
ツールを使用できるようにするには、Claude for Desktop を再起動します。

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 it fetches data without disclosing behavioral traits like rate limits, authentication needs, data freshness, error conditions, or response format. It mentions the source (Buienradar) but not what that implies for reliability or availability.
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 with zero waste—it directly states the tool's function, time scope, and data source. It's appropriately sized and front-loaded, making it easy to parse quickly.
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 no annotations, no output schema, and low schema coverage, the description is incomplete. It lacks details on parameters, return values, error handling, and operational constraints, which are critical for a data-fetching tool with required inputs.
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 0%, and the description provides no information about the parameters (lat, lon). It doesn't explain what these represent (latitude/longitude coordinates), valid ranges, units, or how they affect the data fetched, leaving parameters completely undocumented.
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 ('fetches precipitation data') and resource ('from Buienradar'), with specific time scope ('for the next 2 hours'). It doesn't need to differentiate from siblings since none exist, but could be more specific about what precipitation data includes (e.g., rainfall intensity, probability).
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 is provided on when to use this tool versus alternatives or prerequisites. The description mentions the data source (Buienradar) but doesn't explain limitations or appropriate contexts for use, leaving the agent without operational context.
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 overlap between tools. The tool's purpose is clearly defined and distinct by default.
A single tool inherently has perfect naming consistency, as there are no other tools to compare it against. The naming follows a clear verb_noun pattern (get_precipitation_for).
One tool is too few for a weather data server, as it severely limits functionality. A Buienradar server should ideally include tools for forecasts, radar images, or location-based queries, making this set incomplete and under-scoped.
The tool set is severely incomplete for a weather data domain. It only provides precipitation data for a short timeframe, with no coverage for forecasts, historical data, radar visuals, or other essential weather parameters, leading to significant gaps in functionality.
