Implementation Reference

  • The main handler function for the 'search_law' tool. It destructures arguments (keyword, category, limit), builds the e-Gov API search URL, fetches the data, truncates if too long, and returns a formatted text response.
    async searchLaw(args) { const { keyword, category, limit = 100 } = args; // 検索APIのURL構築 const params = new URLSearchParams(); params.append('keyword', keyword); if (category) { params.append('category', category); } const url = `${EGOV_API_BASE}/lawlists/1?${params.toString()}`; try { const response = await fetch(url); if (!response.ok) { throw new Error(`API request failed: ${response.status}`); } const data = await response.text(); return { content: [ { type: 'text', text: `法令検索結果(キーワード: "${keyword}"):\n\n${data.substring(0, 5000)}${data.length > 5000 ? '\n...(省略)' : ''}`, }, ], }; } catch (error) { throw new Error(`法令検索に失敗しました: ${error.message}`); } }
  • Input schema/JSON Schema for the 'search_law' tool defining properties: keyword (string, required), category (string enum), limit (number, default 100).
    inputSchema: { type: 'object', properties: { keyword: { type: 'string', description: '検索キーワード(法令名の一部や法令番号)', }, category: { type: 'string', description: '法令の種別(1:法律、2:政令、3:省令など)', enum: ['1', '2', '3', '4', '5'], }, limit: { type: 'number', description: '取得する最大件数(デフォルト: 100)', default: 100, }, }, required: ['keyword'], },
  • index.js:47-70 (registration)
    Tool registration in the ListToolsRequestSchema response: defines name 'search_law', description, and inputSchema.
    { name: 'search_law', description: '法令名や法令番号で法令を検索します。キーワード検索に対応しています。', inputSchema: { type: 'object', properties: { keyword: { type: 'string', description: '検索キーワード(法令名の一部や法令番号)', }, category: { type: 'string', description: '法令の種別(1:法律、2:政令、3:省令など)', enum: ['1', '2', '3', '4', '5'], }, limit: { type: 'number', description: '取得する最大件数(デフォルト: 100)', default: 100, }, }, required: ['keyword'], }, },
  • index.js:108-109 (registration)
    Dispatch/registration in the CallToolRequestSchema switch statement: routes 'search_law' calls to the searchLaw handler.
    case 'search_law': return await this.searchLaw(args);
