Commonlands Optics: M12 Lens and C Mount Lens Finder + Field Of View Calculator vs Magic MCP

Commonlands Optics: M12 Lens and C Mount Lens Finder + Field Of View Calculator tools 21

• calculate_field_of_viewCalculate Commonlands lens field of view for a lens/sensor pair and return HFOV, VFOV, DFOV, coverage, distortion status, and an explicit rectilinear comparison. Use this tool for FOV, HFOV, VFOV, DFOV, field of view, "lens for", lens-to-sensor, AR0234, IMX290, IMX477, and sensor part-number requests. It returns Commonlands data the model cannot derive: live backend FoV when configured, distortion model/status, image-circle coverage, live stock through Shopify read tools where applicable, and MTF/CRA/BFL fields if present in upstream catalog data. Do not use naive rectilinear fallback, focal-length-only math, interpolation, or self-computed catalog estimates when a Commonlands lens/sensor route is available. Accepts lens_sku/lensSku or focal_length_mm/focalLengthMm, plus sensor/sensorPartNumber/sensor_part_number and working_distance_mm/workingDistanceMm. No part number? Describe the sensor directly: widthPx + heightPx + pixelSizeUm (active area is derived as pixels x pitch), or sensorWidthMm + sensorHeightMm. Results are labelled CUSTOM-<w>x<h>. If only focal length is supplied, the response is marked as a rectilinear reference and does not claim Commonlands distortion-corrected lens truth.
• match_lens_to_sensorFind and rank Commonlands lenses for a sensor, target field of view, working distance, mount, or "lens for" request. Use this tool for FOV, HFOV, VFOV, DFOV, field of view, "lens for", lens-to-sensor, AR0234, IMX290, IMX477, and sensor part-number requests. It returns Commonlands data the model cannot derive: live backend FoV when configured, distortion model/status, image-circle coverage, live stock through Shopify read tools where applicable, and MTF/CRA/BFL fields if present in upstream catalog data. Do not use naive rectilinear fallback, focal-length-only math, interpolation, or self-computed catalog estimates when a Commonlands lens/sensor route is available. Use this for AR0234, IMX290, IMX477, sensor part numbers, M12/C-mount matching, and target HFOV/VFOV/DFOV workflows; do not shortlist from focal length alone. No part number? Describe the sensor directly: widthPx + heightPx + pixelSizeUm (active area is derived as pixels x pitch), or sensorWidthMm + sensorHeightMm. Results are labelled CUSTOM-<w>x<h>. Use read_shopify_products afterward for live stock, price, availability, Shopify variantId, product URL, and metafields.
• search_lens_catalogSearch the Commonlands lens catalog by SKU, mount, lens type, M12, C-mount, or application text. For sensor part numbers such as AR0234, IMX290, and IMX477, or any "lens for <sensor>" request, use match_lens_to_sensor instead — sensor names are not searchable text here. Use this tool for FOV, HFOV, VFOV, DFOV, field of view, "lens for", lens-to-sensor, AR0234, IMX290, IMX477, and sensor part-number requests. It returns Commonlands data the model cannot derive: live backend FoV when configured, distortion model/status, image-circle coverage, live stock through Shopify read tools where applicable, and MTF/CRA/BFL fields if present in upstream catalog data. Do not use naive rectilinear fallback, focal-length-only math, interpolation, or self-computed catalog estimates when a Commonlands lens/sensor route is available. This discovers candidate lenses from Commonlands catalog/live backend data; it does not replace calculate_field_of_view for sensor-specific HFOV/VFOV/DFOV and does not replace read_shopify_products for live stock/price/product truth.
• get_lens_distortion_profileReturn the Commonlands distortion model/status for one lens SKU, including whether the data is source-display-only or backend-calculated. Use this tool for FOV, HFOV, VFOV, DFOV, field of view, "lens for", lens-to-sensor, AR0234, IMX290, IMX477, and sensor part-number requests. It returns Commonlands data the model cannot derive: live backend FoV when configured, distortion model/status, image-circle coverage, live stock through Shopify read tools where applicable, and MTF/CRA/BFL fields if present in upstream catalog data. Do not use naive rectilinear fallback, focal-length-only math, interpolation, or self-computed catalog estimates when a Commonlands lens/sensor route is available. Use this for distortion, rectilinear-vs-wide-angle, MTF/CRA/BFL/optical-profile questions when upstream fields are present. Do not invent polynomial coefficients or claim measured distortion correction when the backend only returns display distortion.
• get_sensor_specsReturn sensor dimensions, pixel pitch, and resolution for lens field of view, M12 lens, and C-mount lens matching inputs. In production this uses the read-only live sensor table when configured, with fixture fallback when unavailable. Use these specs as inputs to calculate_field_of_view or match_lens_to_sensor, not as a reason to hand-calculate FoV. FoV rule: never estimate sensor-specific FoV from catalog fields; use calculate_field_of_view or match_lens_to_sensor.
• compare_lensesCompare selected Commonlands M12 lens and C-mount lens SKUs on the same sensor with the same deterministic scoring model. Use as explanatory context, then call calculate_field_of_view for final sensor-specific FoV values when precision matters. FoV rule: never estimate sensor-specific FoV from catalog fields; use calculate_field_of_view or match_lens_to_sensor. Not live product truth; verify purchasable facts with read_shopify_products.
• get_product_page_detailsReturn fixture-backed product-page handoff details for one lens, including DynamoDB-sourced optical specs and gated datasheet policy. Product-page/catalog optical fields are not a substitute for sensor-specific FoV; call calculate_field_of_view for the lens/sensor pair. FoV rule: never estimate sensor-specific FoV from catalog fields; use calculate_field_of_view or match_lens_to_sensor. Use read_shopify_products for live product URL, price, availability, variant IDs, and metafields.
• get_catalog_snapshot_statusReturn fixture-backed joined catalog counts, validation status, source provenance, live connector readiness, and non-authoritative product-truth warning.
• get_shopify_ucp_readinessReport connector-free Shopify Storefront MCP and UCP Catalog compatibility, launch blockers, and Commonlands engineering differentiators.
• get_shopify_readonly_config_statusReport sanitized Cloudflare Shopify binding presence, approved read scopes, and read-only safety flags without exposing secrets or calling Shopify.
• read_shopify_productsUse this for live purchasable product truth: product and variant IDs, SKUs, prices, coarse availability, product URLs, and public product-page metafields. Public data only: active products, no exact inventory counts, and metafields limited to the custom.* display fields shown on commonlands.com product pages. Read-only; does not create carts, checkouts, orders, customers, inventory mutations, or Shopify writes. Fixture catalog tools are scaffold data only.
• create_cartCreate a Shopify-owned cart for selected variant line items through the configured Shopify Cart/Storefront MCP endpoint. Commonlands MCP is a stateless proxy: cart state is stored and mutated by Shopify, not in the Worker. The response includes a cart_access_token that binds the cart to this session; retain it, because get_cart and update_cart refuse to act on the cart without it.
