🖥 Desktop Client
Introducing the CowAgent Desktop client for macOS and Windows — your local super AI assistant, truly ready to use out of the box. Download: CowAgent Desktop
Highlights:
- Out of the box: the full Agent runtime is bundled — launch right after install, no need to set up Python or other dependencies
- Full chat experience: streaming replies, session management, tool-call step display, Markdown rendering, plus sending and previewing images / videos / files
- Visual management: configuration, models, knowledge base, scheduled tasks, skills, and memory pages mirror the Web console, all manageable in the native UI
- Channel onboarding: connect messaging channels by scanning a QR code right inside the app
- Auto update: automatic version checks and one-click updates, with download speed optimized across regions
- Native experience: first-run onboarding, follows the system language, and platform-adaptive window interactions
📚 Knowledge Base
- Create & import documents: create new documents or import external ones directly from the UI
- Automatic index maintenance: the knowledge base index is rebuilt automatically from the actual directory tree, preventing index drift or lost documents
- Vectorization fix: the index now reuses the unified embedding provider, ensuring real semantic vectors instead of falling back to keyword search
🔌 On-demand MCP Tool Retrieval
To address context bloat when many MCP tools are connected, we added on-demand tool retrieval: relevant MCP tools are loaded on demand via RAG vector search based on the current task, reducing the context taken up by irrelevant tools. Thanks @fengyl07 Docs: MCP Tools🌏 Traditional Chinese Support
The Web console, logs, and documentation now support Traditional Chinese (zh-Hant); the interface language can follow the system or be switched manually. Thanks @anomixer (#2935)🤖 New Models
- Added support for claude-sonnet-5 and claude-fable-5
- Added support for doubao-seed-2-1-pro and doubao-seed-2-1-turbo
🔒 Security Hardening
- Sensitive file read protection: hardened access to credential and other sensitive files to prevent bypass reads. Thanks @fengyl07 (#2913)
- Browser access protection: blocks browser requests targeting internal network and cloud server internal endpoints, reducing the risk of being tricked into reaching internal services. Thanks @Jiangrong-W
- Safer config parsing: config content is parsed in a safer way to avoid potential code execution risks. Thanks @shunfeng8421
