What Mashvisor (BYOK) is for

Mashvisor (BYOK) lets an AI assistant read your own Mashvisor data through the Mashvisor API with a key you supply (Mashvisor API key). Read-only: 12 tools (list_cities, list_neighborhoods, list_top_markets, get_city_investment_performance, search_listings, get_top_neighborhoods, get_neighborhood_overview, list_neighborhood_schools, get_neighborhood_crime, get_rental_rates, get_city_summary, get_listing_price_trends). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.mashvisor.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Mashvisor. Mashvisor and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which cities in Florida does Mashvisor cover?"
• "Which neighborhoods does Los Angeles have in Mashvisor?"
• "What are the biggest housing markets in Georgia by homes for sale?"
• "What is the median price and rental yield in Los Angeles?"
• "Which 3 bedroom homes under 900000 are for sale in San Francisco?"
• "Which Miami Beach neighborhoods have the highest occupancy?"

BYOK key

You bring your own Mashvisor Mashvisor API key (https://www.mashvisor.com/api-plans). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.mashvisor.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

• https://www.mashvisor.com/api-doc-v2 (the API this connector calls, with a BYOK key)

Live from the Mashvisor API (api.mashvisor.com) with a BYOK key; documentation: https://www.mashvisor.com/api-doc-v2. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Mashvisor. Mashvisor and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your Mashvisor account.

Mashvisor (BYOK) — Privacy Policy

Effective 16 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Mashvisor (BYOK) is. Mashvisor (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Mashvisor data: Read US city and neighborhood real estate market data from Mashvisor: for-sale listings, investment metrics, rental rates, Airbnb occupancy, schools and crime statistics, with your own API key. You bring your own Mashvisor Mashvisor API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Mashvisor call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.mashvisor.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Mashvisor rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Mashvisor receives. The request we make on your behalf, including the key and the arguments, under Mashvisor's own terms and privacy policy (https://www.mashvisor.com/api-plans). Mashvisor acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Mashvisor gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Mashvisor data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Mashvisor (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Mashvisor at any time to end all access.

Children. Mashvisor (BYOK) is a general-audience service operated by the adult using the assistant, under Mashvisor's own age rules.

Changes. We will post changes here with a new effective date.
