Optics

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."

from mcp.client.streamable_http import streamablehttp_client

async with streamablehttp_client("https://mcp.sunex-ai.com/mcp") as (r, w, _):
    async with ClientSession(r, w) as session:
        await session.initialize()
        result = await session.call_tool(
            "recommend_lens_for_imager",
            {"imagerPn": "IMX577", "fNumMax": 2.0}
