How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security89
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token. See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability57
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2136 tokens (~178/item across 12 items; 12 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
- Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage76
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 29% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 12 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

No change was recorded against any check on this day. Stability & Change Management went from 10 to 13. That category is still filling its 30-day observation window: 3 days of observed history at the previous scan, 4 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
analyze_property_investment Analyze an investment property ~182
Gross rental yield, gross annual rent, price-to-rent and price per sq ft for a sale listing, from the user's monthly_rent, an active rental listing for the same property, or a RentCast rent estimate (labelled). With assumptions (down payment, rate, taxes, insurance, vacancy, repairs, management, capex) also cash flow, cap rate and cash-on-cash, plus a sensitivity table. Gross yield is not a return; always relay the disclaimer.

save_property_watchlist Save a property watchlist ~163
Save the user's search criteria once as a named, persistent watchlist (same criteria as search_properties) with alert preferences (min_score, new listings, price drops with optional minimum percent or amount, back on market). Realty.Bingo then monitors the area on a schedule, independent of any conversation, and records new matching listings, price reductions and relistings as alerts. Saving again with the same name replaces it. Returns how the criteria were interpreted (hard vs soft vs excluded) and a preview from stored data. Preferences about the people in a neighbourhood are refused (fair housing).

search_properties Search properties ~616
Find active U.S. homes for sale or rent in a city+state, ZIP codes, a radius around a point, or a polygon. Hard requirements (max_price, min_bedrooms, min_bathrooms, property_types, must_have) filter; soft preferences (ideal_max_price, preferred_bedrooms, nice_to_have, styles) rank; avoid and exclude_property_types exclude. Each result has a 0-100 match score with reasons and uncertainties, the features the listing states (with evidence class), source details and when it was last confirmed active. Features a listing does not mention are UNKNOWN, never assumed. Reuses data fetched in the last 12 hours; otherwise makes a live request if the daily allowance permits. Source: Realtor.com (via RapidAPI) with RentCast as fallback; each result names its source. Never present results beyond what is returned.

How do I install the Realty.Bingo MCP server?
Realty.Bingo is a hosted endpoint at https://realty.bingo/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

What is the Realty.Bingo MCP server?
Realty.Bingo is an MCP server listed in the public MCP registry as io.github.agentstructure/realty. Property search, comparison, investment analysis and watchlists with change alerts. This page covers its hosted endpoint (https://realty.bingo/mcp).
Is the Realty.Bingo MCP server safe to use?
Realty.Bingo scores 74 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the Realty.Bingo MCP server expose?
Realty.Bingo exposes 12 tools: search_properties, get_property_details, save_property_watchlist, manage_property_watchlist, get_property_alerts, and 7 more. Their descriptions and schemas cost roughly 1,897 tokens of context every time the server is loaded.
Does the Realty.Bingo MCP server require authentication?
Yes. Realty.Bingo asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.
Is the Realty.Bingo MCP server still maintained?
Realty.Bingo is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
