Implementation Reference
- src/providers/eul/provider.ts:81-117 (handler)The handleGetDocument method performs the actual retrieval of the EUR-Lex document, handles conversion to markdown, section extraction, and optional file saving.
private async handleGetDocument(args: Record<string, unknown>): Promise<ToolResult> { const { celex, language = 'DE', section, save_path } = args as { celex: string; language?: string; section?: string; save_path?: string; }; logger.info('Fetching EUR-Lex document', { celex, language }); const response = await axios.get(`${CELLAR_BASE}/${celex}`, { headers: { 'Accept': 'text/html, application/xhtml+xml', 'Accept-Language': `${language.toLowerCase()}, en;q=0.8`, }, maxRedirects: 5, responseType: 'text', }); const markdown = this.converter.convert(response.data); validateConversion(markdown, 'EUR-Lex'); if (section) { const extracted = this.extractSection(markdown, section); if (!extracted) { return { content: [{ type: 'text', text: `Section "${section}" not found.` }], isError: true }; } return { content: [{ type: 'text', text: extracted }] }; } const fullDoc = `# ${celex}\n\n---\n\n${markdown}`; if (save_path) { const { writeFile } = await import('fs/promises'); await writeFile(save_path, fullDoc, 'utf-8'); return { content: [{ type: 'text', text: `Saved to ${save_path}\n\nCELEX: ${celex}\nLanguage: ${language}` }] }; } return { content: [{ type: 'text', text: fullDoc }] }; } - Definition and input schema for the 'eul:get_document' tool.
