Once, by hand — no assistant finds servers on its own yet. Then ask it something like “Compare the villa regimes on Seabrook Island by price per square foot” or “What would a 1,400-square-foot villa in Pelican Watch sell for?”
- ClaudeOn the web or desktop app: Customize → Connectors → + Add → Add custom connector. Paste the address, choose “No sign in”, then Add.Free plans get one custom connector; not from the phone app. On Team and Enterprise, an owner adds it first.
- ChatGPTAt chatgpt.com/plugins: + → Add custom MCP server. Paste the address and pick No Authentication.Not on Free. On Plus and Pro it can sit behind Developer mode (Settings → Security and login), and some plans may read here without being able to send Mike a note.
- GeminiOn the web: Settings → Connected Apps → Add a custom app, then paste the address.Web only to add (it then shows on the phone). US, 18 and over, a personal account; Google may limit it to paid plans.

The tools
- list_neighborhoodsEvery neighborhood and villa regime on Kiawah or Seabrook Island: type, area, regime manager, MLS sales since 2021 and the median price per square foot over the last 24 months where five or more sales allow. Facts about places only.
- get_neighborhoodOne neighborhood's full record: sourced facts (each with who published it), regime manager, the county's homes and lots, its MLS sales by year, the living-CMA price-per-square-foot range, what it costs to own (fee ledger lines) and the page URL.
- island_marketKiawah or Seabrook Island home sales from 2021-01-01 to the last pull (2026-10-14), checked month by month against the MLS's own statistics: the last 12 months, each year's price per square foot and price-cut share, each price band's days on market and months of supply, and what cutting the price has meant for sellers.
- estimate_rangeArithmetic, not a price opinion: the middle half of closed-sale price per square foot (25th–75th percentile) for a complex, or for attached or detached homes island-wide, times the given heated square feet. For a real CMA, send the person to request_contact.
- feesThe fee ledger for Kiawah or Seabrook Island: each buyer, owner and rental charge with its amount, who charges it, how sure it is (confirmed / secondary / conflicting / not published), its source and the date it was checked.
- request_contactSends the person's question to Mike Olson, a licensed South Carolina real estate agent with eXp Realty, LLC. Only call this when the person asked you to. It never carries consent to calls or texts — Mike emails the person himself to confirm before anything else.
The rules every answer follows
- Facts about places only — never who lives somewhere. The Fair Housing Act applies to every word, from a page or a tool.
- Every MLS figure is an aggregate of closed sales, checked month by month against the MLS’s own statistics before it’s published; medians need five sales. Quote the attribution line and the dates.
- Fees marked secondary, conflicting or not published aren’t settled. Say so when you quote them.
- The range tool is arithmetic on past sales, not an appraisal or a price opinion. A real CMA comes from Mike Olson.
- request_contact only when the person asked you to. An agent can’t agree to calls, texts or a mailing list for someone — Mike Olson emails the person himself to confirm before anything else, and nothing automated is sent.
