Tool names and descriptions exactly as the server reported them on Nov 9, 2026. The maker wrote them, not us; we show them as plain text.
simplyrets_get_account_infoWhat these API credentials can reach: the MLS vendor ids (needed as `vendor` on multi-MLS apps), the time of each vendor's last sync, usernames and the available endpoints (/properties, /openhouses, /agents, /offices, /properties/analytics). OPTIONS /.
simplyrets_get_feed_metadataValues present in an MLS feed, to build valid searches: statuses, property types, cities, counties, neighborhoods, areas and features, plus the last sync time. OPTIONS /properties.
simplyrets_search_listingsSearch MLS listings (SimplyRETS /properties): by keyword, status, type, price, beds, baths, area, year, city, zip, neighborhood, agent, broker, features or a map polygon. Returns address, price, status, photos, agent, office, property details and remarks, without empty fields. Pa
simplyrets_get_listingOne listing by its SimplyRETS id (`mlsId`, the number in search results; NOT the public MLS number `listingId`). Full detail: address, geo, price, photos, agent, office, property, school, tax, remarks. GET /properties/{mlsId}.
simplyrets_list_open_housesUpcoming open houses with the listing they belong to: filter by property type, listing id, city, broker, agent, price, size, beds, baths and start date. Page with next.offset or next.lastId. GET /openhouses.
simplyrets_get_open_houseOne open house by its key (the `openHouseKey` of a list result). GET /openhouses/{openHouseKey}.
simplyrets_list_agentsThe agent roster of the MLS feed: id, name, address, contact and office. Needs the Agents API add-on on your SimplyRETS app (the demo credentials return an empty list). GET /agents.
simplyrets_list_officesThe brokerage office roster of the MLS feed, newest modification first. Needs the Offices API add-on on your SimplyRETS app (the demo credentials cannot use it). Pass count=true for the total. GET /offices.
simplyrets_get_market_analyticsStatistics for the listings a search matches (same filters as simplyrets_search_listings): total count, average price, bedrooms, full baths, living area, lot size and year built, and the number of listings per area. Use it for market summaries of a city, zip or price band. GET /p
simplyrets_get_listing_analyticsAnalytics for one listing, such as its price per square foot. GET /properties/{mlsId}/analytics.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed yesterday, and the latest version (1.23.1) reached the registry yesterday.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
