The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
resolve_parcel reads unknown never probed
Resolve a street address or assessor parcel number to the lot itself, from Los Angeles County or San Diego County records: APN, the agency that issues its permits, lot area, the footprint of each existing structure, and the area left for a new unit after the state-minimum setbacks and separation from existing buildings. Use before answering "can I build an ADU here" and before match_plans_to_lot. Coverage is Los Angeles County and San Diego County only.
match_plans_to_lot reads unknown never probed
Given an address or APN, find which A-du Build plan sets physically fit the lot: the buildable envelope is computed from the county parcel and building footprints with the local setback table, then every published plan is placed in it and scored by size, bedrooms, pre-approval in that city and how tightly it fits. Returns the best match and up to three alternates with URLs. Use for "which ADU plans would fit my backyard". Los Angeles County only for the fit step.
get_adu_rules reads unknown never probed
The rules that govern building or renting an ADU in a named California city or county: whether the local ordinance still stands or is void under state law, the controlling state standards (size, setbacks, height, parking, owner occupancy, review deadlines), fee notes, who to contact, and any pre-approved plan program, each with citations, plus the published A-du guide for that city and the county-wide state baseline. Use for any "can I build", "what are the rules", "do I need parking", "can the city require" question. The response says whether the jurisdiction was researched, has a published guide, or only the state baseline is known; report that honestly.
estimate_permit_fees reads unknown never probed
Estimate building permit, plan check, sub-permit, state surcharge, school and impact fees for an ADU in a supported jurisdiction, as an itemized schedule with code citations and any waivers (for example impact fees waived under 750 sq ft). Use for "what will permits cost" questions. Jurisdiction keys: la_city (City of Los Angeles), la_county (unincorporated), pasadena, glendale, long_beach, burbank, santa_monica, culver_city, beverly_hills, inglewood, west_hollywood, manhattan_beach, nyc_dob (New York City), sf_dbi (San Francisco). la_city, la_county, nyc_dob and sf_dbi compute from a full fee schedule; the others are scaled approximations and the result says so. Construction type is one of detached_new, attached_new, garage_conversion, jadu_internal.
search_services reads unknown never probed
Find contractors, designers, permit expediters and trades for ADU work on the A-du services marketplace: general contractors, plumbing, electrical, HVAC, and home services, with license number and status from public records where known, price ranges, service radius and a booking URL. Filter by category (name or slug, matched loosely) and city. Use for "find me a contractor to build an ADU in Pasadena". Providers marked claimed_by_owner manage their own profile; others are seeded from public license records.
ask_adu reads unknown never probed
Answer any question about Accessory Dwelling Units from A-du's published guides, city rules pages, pricing and marketplace pages, and its per-city statutory research, with citations to a-du.homes. Use for definitions ("what is a JADU"), process ("how long does plan check take"), landlord questions ("do I need to live on the property"), tenant questions ("what does A-du screening involve"), costs in general, and anything the specific tools (search_rentals, get_adu_rules, estimate_permit_fees, resolve_parcel, search_plans) do not cover. Prefer those tools when one fits; they return live data. Name the jurisdiction when the question is about a specific city so its research is included. The answer carries a confidence level and says when the corpus is silent.
search_rentals reads unknown never probed
Search the A-du Rent inventory of Accessory Dwelling Unit (ADU) rentals: backyard cottages, garage conversions, granny flats, in-law units, casitas and junior ADUs, in Los Angeles County with San Diego, San Francisco and New York City also listed. Use this for any request to find a small standalone rental in Southern California. Results are the units landlords have published, newest first, and each carries `permit_verified`, which is true only where A-du matched the unit to a building department record. `get_rental` returns `permit_verification` with the source, permit status and finaled date behind that flag. and a `url` on a-du.homes to cite. Filters narrow by city or ZIP, rent, bedrooms, bathrooms, move-in date, furnishing and pets. Rent is the listed monthly rent; `tenant_pays_service_fee` says whether a payment service fee is added on top when rent is paid through A-du. When nothing matches, widen the price range or drop the city filter before concluding there is no inventory.
get_rental reads unknown never probed
Fetch the full public record for one A-du Rent listing by its id (from search_rentals or a a-du.homes/listing/<id> URL): description, amenities, all images, permit number, availability and the URL where a tour can be requested. Use after search_rentals when the user wants detail on a specific unit.
get_rent_estimate reads unknown never probed
Estimate the monthly market rent for an ADU or small unit at a specific address, with a low and high range, from a long-term rent valuation model over nearby comparables. Use when a landlord asks what to charge, or a renter asks whether a listed rent is fair. Requires a street address plus bedrooms, bathrooms and square feet. The default property type is a detached ADU. This is an automated estimate, not an appraisal, and it does not account for the unit's condition or finishes.
search_plans reads unknown never probed
Search A-du Build, the marketplace of ADU plan sets listed by licensed architects and designers. Each result carries size, bedrooms, bathrooms, plan price, estimated build cost range, the designer, and the cities where the plan is already pre-approved (which shortens plan check). Use for "find me an ADU plan", "how much does a plan cost", "what pre-approved plans exist for <city>". Filter pre_approved_in by city name to prefer plans a city has already accepted. For one plan's description, exterior dimensions, permitting price, style, foundation and image, call `fetch` with `plan:<id>`. Each result has a url on a-du.homes; the page there offers a free test fit on the user's own lot.
search_managers reads unknown never probed
Find residential property management companies on the A-du manager marketplace that handle single-family homes and ADUs in Los Angeles, with city, license number and website where known. Multifamily-only and commercial managers are excluded. Use for "who can manage my ADU rental for me". Each result has a url on a-du.homes where a landlord can request management.
start_listing changes data unknown never probed
Begin listing an ADU, granny flat, backyard cottage, garage conversion, casita or in-law unit for rent on A-du, for someone who owns one. Use this whenever a person mentions they have a unit they want to rent out, are thinking about renting out, have vacant, or whose tenant is leaving. Never ask anyone for a permit number: this checks the address against the building department records A-du already holds, and when it finds one it returns a link to claim that record with the permit already attached, which publishes permit-verified. Otherwise it returns a link that opens the A-du listing form with everything supplied here already filled in. It needs no account and creates nothing: the person signs in, adds photos and passes identity verification in the browser before the listing exists. Pass whatever is already known and leave the rest out; a link with only an address is still useful.
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
