与AI代理协作创建和探索美人鱼图（TUI + MCP服务器）
概览
Nereid 是一个面向终端优先、用于美人鱼支持图的工作区。它结合了 ratatui TUI、模型上下文协议（MCP）服务器、基于文件夹的会话持久化和确定性文本渲染，使人类和 AI 代理能够检查并更新同一图解会话。 - 从终端浏览和编辑序列图、流程图、类图、实体-关系（ER）和甘特图，- 将图表、攻略、交叉引用、选择和活动状态保存在本地会话文件夹中，- 提供用于图表导航、结构化变异（包括序列块）、xref、攻略和图查询的类型MCP工具，- 当指纹仍匹配时，用保持身份的调和替换Mermaid源，- 导出Mermaid源及文本预览，支持可审阅的文件式工作流程。 Nereid 仅供非商业用途使用。

想用奈瑞德时：
- 从终端浏览和编辑序列、流程图、类、实体关系（ER）和甘特图，
- 将图表、攻略、交叉引用、选择和活动状态保存在本地会话文件夹中，
- 提供用于图表导航、结构化变异（包括序列块）、xref、通关和图查询的类型化MCP工具，
- 当指纹仍匹配时，用保持身份的调和替代美人鱼来源，
- 导出美人鱼源码及文本预览，支持可审阅的文件工作流程。

nereid
Nereid is a terminal-first workspace for Mermaid-backed diagrams. It combines a ratatui TUI, a Model Context Protocol (MCP) server, folder-based session persistence, and deterministic text renders so humans and AI agents can inspect and update the same diagram session.
Use Nereid when you want to:
- browse and edit sequence, flowchart, class, entity-relationship (ER), and Gantt diagrams from a terminal,
- keep diagrams, walkthroughs, cross-references, selections, and active state in a local session folder,
- expose typed MCP tools for diagram navigation, structured mutation (including sequence blocks), xrefs, walkthroughs, and graph queries,
- replace Mermaid sources with identity-preserving reconcile when fingerprints still match,
- export Mermaid sources plus text previews for reviewable, file-based workflows.
Nereid is source-available for noncommercial use only. Commercial use, product use, paid service use, internal business use, redistribution, sublicensing, or modified distribution requires separate written permission. See License.
Recent releases
- 0.9: Added class, entity-relationship, and Gantt diagrams across parsing, text rendering, the TUI, persisted sessions, and typed MCP reads. The built-in demo now covers all five diagram families.
- 0.8: Added structured sequence block and section ops plus
diagram_replace_from_mermaid, which reconciles stable identities during bulk Mermaid rewrites and reports dangling xrefs. - 0.7: Added the fuzzy
:diagram switcher and persisted Frigg symbol anchors for sequence participants and flowchart nodes.
See CHANGELOG.md for the complete release history.
