one-roof
Unified UK property search across major portals with deduplication and open-data enrichment, enabling natural-language queries for listings, sold prices, EPC, crime, schools, and market stats.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
searchSearch UK homes for sale or rent across every portal. Returns result ids to pass to `fetch`.
fetchFetch full detail + open-data enrichment for a result id from `search` (portal:listingId).
resolve_locationTurn free text like 'Clapham', 'near Leeds station', or 'SW11' into structured geography (outcodes, centroid, per-portal identifiers). Call this first; feed its result into search_listings.
search_listingsPrimary tool. Federated live search across every portal (Rightmove, Zoopla, OnTheMarket), deduplicated across portals and enriched with open data (last-sold price, EPC floor area, £/sqft, council tax, flood, crime, schools). Returns a coverage flag so truncation is never silent.
get_listingFull detail plus full open-data enrichment for one listing, by portal and portal listing id.
get_property_intelligenceEverything known about an address or UPRN from open data alone — no live listing required. Sold history, EPC (incl. true floor area), council tax band, flood risk, crime density, nearby schools + Ofsted, planning, broadband. Works with zero scraping.
market_statsArea-level market stats: asking vs achieved prices, £/sqft distribution, rental yields, average time on market, from Land Registry + live listings.
compare_listingsNormalised side-by-side comparison of several listings on price, £/sqft, EPC, and enrichment.
commute_searchFilter listings by travel time to a destination — e.g. '<=30 min to Canary Wharf by public transport' — using an isochrone.
find_comparablesRecent nearby Land Registry sales matched on property type, size, and bedroom count — the comparables a surveyor would use.
track_searchPersist a search and, on later calls, surface listings that are new or reduced since last check.
list_sourcesProvenance for the last search: which portal adapters ran, whether each was ok/degraded/blocked, cache age, and whether coverage was complete or truncated. Use this to trust or caveat results.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
12/12 tools missing one or more hints — search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); fetch (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); resolve_location (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +9 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool handlers catch errors
Only 0/2 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 2/12 tools referenced in tests (17%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 7 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
