Implementation Reference

• src/index.ts:147-154 (handler)

  Primary MCP tool handler for list_snippets: wraps engine.ListSnippets and returns JSON-formatted response

  private async listSnippets(args: any): Promise<GenericMCPResponse> {
    return {
      content: [{

        text: JSON.stringify(await this.engine.ListSnippets(args), null, 2)
      }]
    };
  }

• src/engine/local_storage.ts:28-46 (handler)

  Core implementation of snippet listing with filtering by language, tag, and title

  async ListSnippets(query?: SnippetQuery): Promise<CodeSnippet[]> {
    // 単一のfilter関数で全フィルタリング条件を処理
    return this.snippets.filter(s => {
      if (query) {
        if (query.language && s.language.toLowerCase() !== query.language.toLowerCase()) {
          return false;
        }
  
        if (query.tag && !s.tags.some(t => t.toLowerCase() === query.tag!.toLowerCase())) {
          return false;
        }
  
        if (query.title && !s.title.toLowerCase().includes(query.title.toLowerCase() || '')) {
          return false;
        }
      }
      return true;
    });
  }
