v2.0.9

🖥️ Model Management Console

The Web Console adds a new Models page that organizes everything by provider × capability, covering chat, image, voice, embedding and search models in one place:

Per-provider configuration: Each provider's API Key / API Base is configured once at the top, and every capability below picks it up automatically — no more re-entering credentials
Image models: Image understanding and image generation can each pick their own provider and model independently; falls back to the main model when unspecified
Voice models: ASR (speech-to-text) and TTS (text-to-speech) can be configured independently, with new Qwen and Zhipu ASR/TTS models added
Embedding models: Configurable embedding models (used for memory and knowledge-base retrieval), with new support for OpenAI, Tongyi, Doubao, Zhipu and others; run /memory rebuild-index after switching to rebuild the index online
Search capability: Web search has been upgraded to support Bocha, Baidu, Zhipu and more providers — in auto mode the agent can synthesize results from multiple sources for deeper research

🧩 MCP Protocol Support

Adds support for MCP (Model Context Protocol), expanding from a fixed built-in toolset to an open, pluggable tool ecosystem — any MCP-compatible service can be plugged in directly as an agent tool.

Native JSON-RPC implementation, zero extra dependencies, supports both stdio and sse transports
Compatible with the mcpServers configuration style used by Claude Desktop / Cursor, reads ~/cow/mcp.json by default

Documentation: MCP Tools. Thanks @yangluxin613 (#2801)

For sites that require login or have anti-bot protection, the browser tool can now persist a login session for long-term reuse, and supports attaching to your real Chrome browser to bypass fingerprint detection:

Persistent user profile (default): Uses ~/.cow/browser_profile as the browser user data dir by default; once logged in, sessions are reused automatically on subsequent runs
CDP mode: Configure tools.browser.cdp_endpoint to take over a real Chrome instance with full browser permissions

Documentation: Browser Tool. Thanks @leafmove (#2809)

🤖 New Models and Improvements

New models: gpt-5.5, gemini-3.5-flash, qwen3.7-max, ernie-5.1
Improvements: DeepSeek V4 supports the reasoning_effort thinking-depth parameter; fixed thinking models like MiMo failing to connect via the OpenAI-compatible protocol

🔒 Deployment & Security

Bind to localhost by default: The Web Console web_host now defaults to 127.0.0.1; for server deployments, set it to 0.0.0.0 and configure a password manually. Thanks @August829, @yidaozhongqing, @YLChen-007, @icysun
Fully bundled frontend assets: All third-party CSS / JS are now served locally — the console works offline and on intranet deployments. Thanks @gitlayzer (#2816)
