Bird Id

Bird species identification MCP server. YOLO detection + ConvNeXt classification, outputs Top-5 species with confidence and Chinese names.

Install & Run

# Run directly with uvx (auto-installs)
uvx bird-id-mcp

# Or install from git
pip install git+https://github.com/Hakureirm/bird-id-mcp.git
bird-id-mcp

Models are automatically downloaded from HuggingFace on first run (~50MB default).

Model Selection

Model	Size	Speed (x86 1T)	Accuracy
S1v2 (default)	37MB	~150ms	Good
ConvNeXt	144MB	~600ms	Best

Default is S1v2 (fast + small). To use ConvNeXt:
