使用 MCP 工具前必须先装好 Python、Node.js 和 uv,否则工具功能不可用;项目依赖原生模块,需在对应平台打包,macOS 打包还需配置 APPLE_TEAM_ID、APPLE_ID、APPLE_ID_PASS 做公证;本地知识库依赖内置 bge-m3 嵌入模型,首次使用可能需等待模型就绪

Behind the scenes
Most of the recent work happened under the hood, it mainly focuses on stability and long-term reliability.
We rewrote the data layer, consolidating SQLite and LanceDB into PGlite, and reworked the MCP protocol layer to improve tool execution and enable resource- and prompt-level support.
We have ambitious plans for 5ire in 2026 — and recent work is about laying a solid foundation to make that possible.

What's New
Data layer fully rebuilt.
We’ve migrated the storage engine from SQLite + LanceDB to pglite. This refactor doesn’t introduce new features yet, but it lays a solid foundation for upcoming improvements and enhanced capabilities. Updating is recommended to stay compatible with future releases.
Update Strategy Change
Auto-update disabled. Future versions will no longer install automatically. Instead, you’ll receive a notification when a new version is available and can update manually at your convenience.
📌 Notes
Existing data will be migrated automatically during the upgrade.

Before to activating tools feature, ensure the following components are installed:
- Python
- Node.js
- uv (Python package manager)
These components are required as they constitute the runtime environment for the MCP Server. If you don't anticipate using the tools feature immediately, you may choose to skip this installation step and complete it later when the need arises.
For detailed installation instructions, please see our Installation Guide.

Features
⚒️ Support Tools via MCP Servers
MCP is an open protocol that standardizes how applications provide context to LLMs. Think of MCP like a USB-C port for AI applications. Just as USB-C provides a standardized way to connect your devices to various peripherals and accessories, MCP provides a standardized way to connect AI models to different data sources and tools.
With tools, you can access the file system, obtain system information, interact with databases, access remote data, and more, rather than just having a simple conversation.

We have created an open marketplace for MCP Servers. it empowers users to discover exceptional tools while offering a streamlined process for sharing their own MCP server creations.

💡 Local Knowledge Base
We have integrated the bge-m3 as our local embedding model, which excels in multilingual vectorization. 5ire now supports parsing and vectorization of docx, xlsx, pptx, pdf, txt, and csv documents, enabling storage of these vectors to power robust Retrieval-Augmented Generation (RAG) capabilities locally.

📈 Usage Analytics
By keeping track of your API usage and spending, you can gain a better understanding of how much you're spending on the API and make informed decisions to optimize your use of the service.

✨ Prompts Library
The prompt library provides an effective way to create and organize your own prompts. These prompts are highly versatile, thanks to their support for variables.

🔖 Bookmarks
You can bookmark each conversation, and even if the original messages are deleted, the saved bookmarked content remains unaffected.

🔍 Quick Search
You can perform keyword searches across all conversations, quickly pinpointing the information you need.

[!TIP] Since 5ire uses native dependencies, it needs to be packaged on the corresponding platform. If it is on Mac OS, you may also need to configure APPLE_TEAM_ID, APPLE_ID, and APPLE_ID_PASS for notarization to avoid security alerts.
