request_contactSends the person's question to Mike Olson, a licensed South Carolina real estate agent with eXp Realty, LLC.No findings
Why it is in this group
- The name "request_contact" says "request": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
Description, as the server wrote it
Sends 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.

Description, as the server wrote it
One street address in Charleston County: FEMA's flood zone and base flood elevation at the point the Census geocoder places it, the map panel and its date, whether it is inside a town or the City of Charleston, the county tax district, and the ground's height from USGS lidar. Live calls to the government services named in sources. A geocoded point, not a survey — the person confirms on the parcel's elevation certificate.

Description, as the server wrote it
What's happening on the islands and across Charleston, as one list cut on the islands' clock: the Towns' and the library's calendars, the music venues' own feeds (the Charleston Pour House, the Royal American), the year's big dates, the special events, what venues posted and a person approved, and a weekly sweep of the venues with no feed. Every item carries its organizer's page; the door price is as the venue lists it. Use when = today, tomorrow, weekend, week (next 7 days) or all (next 3 weeks); tag = Music for live music.

Description, as the server wrote it
The island directory: 193 real places on Kiawah, Seabrook, Johns Island, Wadmalaw and the Charleston area — restaurants, coffee, groceries, golf, beaches and parks, charters, fishing, places to stay, vacation rentals, health care, pets, home services, home watch and the towns — each with what it is, its address, phone and website, from its own site.

Description, as the server wrote it
The site's true-cost calculator: for a price on Kiawah, Seabrook or Johns Island, the buyer's closing costs, the first year of owning (property tax, association dues, base utilities), what comes later and the seller's side — each line from the fee ledger with how sure it is. An estimate from published fees, not a closing statement or tax advice.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

8 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
