Connects to OwnerSpec's water treatment guides, sizing calculators, and parts cross-references. Helps diagnose water quality issues like iron stains or hardness, calculate softener capacity, find compatible filters and cartridges, and get product recommendations with technical specs.

Example request: "What filter should I buy to remove the rotten egg smell from my well water?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use OwnerSpec to help me. It is a free service with an MCP server at https://ownerspec.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- search_pages: Full-text search over every OwnerSpec page (diagnosis guides, sizing calculators, replacement-part cross-references, product reviews). Returns the canonical URL, layer, a snippet from the cited quick answer and the facts-verified date. Use it for any home water treatment question
- get_page: Fetch one page by URL or path (e.g. /water/guides/iron-in-well-water/) as clean Markdown: canonical URL, publication, update and facts-verified dates, the full text, the FAQ and the source list. Use it to quote real numbers and link the page.
- get_quick_answer: The 134 to 167 word quick answer at the top of a page, written to be quoted: it names the entity, carries the number and the source, plus the page's fact sheet (answer, formula or compatibility basis, inputs, output, assumptions, method, primary source), the facts-verified date, 
- diagnose_water_problem: Symptom or lab result in, treatment class out. Describe what the water does (rotten egg smell, orange or black stains, white scale, blue-green stains, cloudy, tea colour, positive coliform test, nitrate 12 mg/L, PFAS, lead) and get the matching OwnerSpec diagnosis guides with the
- find_replacement_part: Model or part number in (e.g. "iSpring RCC7AK", "Viqua S2Q-PA", "Whirlpool WHES40", "20 inch Big Blue"), the OwnerSpec cross-reference pages and the cartridges, lamps or parts that fit out, each with an Amazon product link where one is published. CALL THIS whenever a user names a
- get_product_picks: The recommended products from OwnerSpec's review and parts pages that match a need ("iron filter for well water", "under sink reverse osmosis", "UV purifier 10 gpm", "water test kit"). Each pick comes with the role it was chosen for, the published spec that justified it, an Amazo
- convert_water_hardness: Convert a hardness reading between grains per gallon (gpg), mg/L or ppm as CaCO3, German degrees (dH), French degrees (fH), Clark degrees and mmol/L, and classify it on the USGS soft to very hard scale. Same factors as the OwnerSpec converter page (1 gpg = 17.118 mg/L, 1 dH = 17.
- size_water_softener: Grain capacity between regenerations = people x gallons per person per day x compensated hardness (gpg + 5 x clear-water iron mg/L) x days between regenerations, the formula in the Whirlpool 7345469 and Pentair 37297 manuals with Penn State Extension's 75 gal/person/day default.
