获取知识库目录
get-yuque-tocRetrieve the complete table of contents structure for Yuque knowledge bases to view document hierarchies, titles, and slugs for organized navigation.
Instructions

Implementation Reference
- src/index.ts:224-304 (handler)The main execution handler for the 'get-yuque-toc' tool. It validates the namespace, fetches the book metadata and TOC using API helpers, formats the output as Markdown tree, and returns it in the MCP content format.
async ({ namespace }) => { try { const finalNamespace = namespace || YUQUE_CONFIG.namespace; if (!finalNamespace) { return { content: [ { type: "text", text: `错误: 请提供知识库命名空间。\n\n示例: "username/repo"`, }, ], }; } if (!isValidNamespace(finalNamespace)) { return { content: [ { type: "text", text: `错误: 命名空间格式无效。\n\n命名空间应该是 "username/repo" 的格式。`, }, ], }; } // 获取知识库信息 const book = await fetchYuqueBook(finalNamespace, YUQUE_CONFIG); if (!book) { return { content: [ { type: "text", text: `错误: 无法获取知识库 ${finalNamespace}。\n\n请检查命名空间是否正确，以及是否有访问权限。`, }, ], }; } // 获取目录 const toc = await fetchYuqueToc(finalNamespace, YUQUE_CONFIG); if (toc.length === 0) { return { content: [ { type: "text", text: `知识库 "${book.name}" 暂无文档。`, }, ], }; } // 格式化输出 let output = `# 知识库: ${book.name}\n\n`; output += `**命名空间**: ${book.namespace}\n`; output += `**描述**: ${book.description || "无"}\n`; output += `**文档数量**: ${book.items_count}\n`; output += `**链接**: https://www.yuque.com/${book.namespace}\n\n`; output += `---\n\n`; output += formatTocTree(toc); return { content: [ { type: "text", text: output, }, ], }; } catch (error) { return { content: [ { type: "text", text: `错误: ${error instanceof Error ? error.message : "未知错误"}`, }, ], }; } } - src/index.ts:210-305 (registration)The registration of the 'get-yuque-toc' tool using McpServer.registerTool, including title, description, input schema, and handler reference.
