calculate_field_of_view Calculate Commonlands field of view ~475
Calculate 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. If only focal length is supplied, the response is marked as a rectilinear reference and does not claim Commonlands distortion-corrected lens truth.
| Name | Type | Req | Description |

compare_lenses Compare Commonlands lenses ~134
Compare 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.

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_specs Get sensor specs ~126
Return 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.

match_lens_to_sensor Match Commonlands lenses to a sensor ~386
Find 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. Use read_shopify_products afterward for live stock, price, availability, Shopify variantId, product URL, and metafields.

prepare_shopify_purchase_handoff Prepare Shopify purchase handoff ~124
Build a read-only Shopify-native purchase handoff seam for a selected lens without creating carts, checkout, orders, inventory mutations, or writes. Preserve any computed FoV provenance from calculate_field_of_view/match_lens_to_sensor when carrying optical context into purchase handoff. FoV rule: never estimate sensor-specific FoV from catalog fields; use calculate_field_of_view or match_lens_to_sensor.
| Name | Type | Req | Description |

read_shopify_products Read Shopify products ~188
Use 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.
| Name | Type | Req | Description |
|---|---|---|---|
| handle | string | — | Optional Shopify product handle. |

search_catalog Search UCP catalog ~109
Fixture-backed UCP Catalog search alias for Shopify-native product discovery; no live Shopify calls or cart behavior. Use this only for broad discovery; when a sensor or target FoV is involved, call match_lens_to_sensor or calculate_field_of_view instead of estimating from catalog fields. FoV rule: never estimate sensor-specific FoV from catalog fields; use calculate_field_of_view or match_lens_to_sensor.
| Name | Type | Req | Description |
|---|---|---|---|
| catalog | object | — | — |
| meta | object | — | Optional UCP agent metadata. |
No output schema declared.
No examples provided.
search_lens_catalog Search Commonlands lens catalog ~289
Search 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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | — | — |
| query | string | — | SKU, title, mount, lens type, application, sensor, or field-of-view search text. |

submit_rfq Submit an RFQ or question to Commonlands ~229
Forward a buyer request-for-quote or engineering question to the Commonlands engineering team. Use after the buyer provides their question and a reply-to email. The recipient is fixed to the Commonlands inbox (the agent cannot choose it); this only sends an inquiry and never creates an order, charges a card, or writes Shopify/customer data. Include part numbers, sensor, quantity, and application when known so the team can reply with a quote. Commonlands replies by email.
| Name | Type | Req | Description |
|---|---|---|---|
| application | string | — | Optional application note. |
| company | string | — | Optional company name. |
| string | yes | The buyer's reply-to email so Commonlands can respond. | |

update_cart Update Shopify cart ~101
Update a Shopify-owned cart through the configured Cart/Storefront MCP endpoint. With UCP endpoints, treat updates as full-state PUT semantics; with the confirmed standard Storefront MCP endpoint, Commonlands maps line_items to Shopify add_items, update_items to quantity changes, and remove_line_ids to explicit removals. Quantity 0 in update_items removes a line.
