Sunex Optics MCP Server
A public Model Context Protocol server that lets AI assistants search Sunex's lens and imager catalog in natural language.
Live endpoint: https://mcp.sunex-ai.com/mcp
Landing page: sunex-ai.com
Transport: Streamable HTTP (MCP spec 2025-03-26). Legacy SSE endpoint at /sse preserved for older clients.

Five tools
| Tool | What it does |
|---|---|
recommend_lens_for_imager | Give it an imager PN → compatible lenses with FOV and angular resolution. One shot. |
search_imagers | Find sensors by PN, manufacturer, or resolution class. |
get_imager_detail | Full sensor specs plus computed geometry (width / height / diagonal in mm). |
find_compatible_lenses | Given pixel count + pitch, return lenses whose image circle covers the sensor. |
search_products | Full catalog search by PN or keyword, with sample pricing and RFQ links. |
Example prompts
- "Recommend a wide-angle lens for the Sony IMX577 with F/2.0 or faster."
- "I need fisheye lenses under $100."
- "What's the diagonal of the IMX477 in mm?"
- "Find lenses for a 1920×1080 sensor with 3µm pixels, 100–180° HFOV."
