Values you fill in

ONEHOME_TOKEN env
Bearer token for services.onehome.com. Paste the raw JWT (Authorization header value, minus the 'Bearer ' prefix) from your signed-in portal.onehome.com session.
ONEHOME_MAGIC_LINK env
Magic-link URL with ?token=... from your real-estate agent. The MCP extracts the token query param and uses it directly as the bearer.
ONEHOME_WS_PORT env
Override the fetchproxy WebSocket port (default 37149). Only used when ONEHOME_TOKEN / ONEHOME_MAGIC_LINK are unset and the MCP boots in capture-from-tab mode.
ONEHOME_COMMUNITIES_FILE env
Path to a JSON array of community names used for feature extraction; overrides the built-in Lake Lure / mountain-NC default vocabulary.
FETCHPROXY_WS_HOST env
Bind interface for the fetchproxy concentrator, a literal IP only (default 127.0.0.1). Keep on loopback; it exists for hosted deployments that run each MCP in its own network namespace.
FETCHPROXY_IDENTITY_DIR env
Absolute path where the fetchproxy long-term identity keypair is stored (default ~/.fetchproxy/identity/).

Common questions

Is Onehome MCP safe?

It passed 2 of 2 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.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (1.2.1) reached the registry 7 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

onehome-mcp

MCP server for OneHome (CoreLogic) — search the listings your real-estate agent curated for you, fetch property details + photos, compare houses side-by-side, and run mortgage / affordability math from within Claude.

Sister project to zillow-mcp, redfin-mcp, compass-mcp, and homes-mcp. Same tool ergonomics — different upstream auth model.

This project was developed and is maintained by AI (Claude). Use at your own discretion.

What's different about OneHome

OneHome isn't a public listings site. Buyers usually reach it through a magic link an agent emails them — https://portal.onehome.com/...?token=eyJ.... That token query param IS the per-user bearer that the portal SPA hands to every GraphQL request.

So instead of routing every fetch through your signed-in browser tab (like the other realty MCPs), onehome-mcp talks directly to services.onehome.com/graphql from Node, with Authorization: Bearer attached. We support three ways to source that bearer:

Mode	How to enable	Notes
`env_token`	`ONEHOME_TOKEN=`	Paste the raw bearer from devtools Network panel. Most direct.
`magic_link`	`ONEHOME_MAGIC_LINK=https://portal.onehome.com/...?token=...`	Paste the full URL your agent sent — we extract the `token` param.
`fetchproxy_capture`	(no env) + ContextMint Bridge browser extension installed (Chrome: load the release's chrome zip unpacked; Safari isn't available yet — it will ship inside the ContextMint app, so use Chrome for now) + signed-in `portal.onehome.com` tab	We wait for your tab to fire any GraphQL request, snapshot the Authorization header, and reuse it.

ContextMint Bridge is the fetchproxy browser extension under its new name, from the same maintainer — fetchproxy's own README (fetchproxy#extension) points to it. Its source is public at nullnet-app/contextmint-bridge: build it yourself, or check a release zip against the .sha256 file published beside it (shasum -a 256 -c contextmint-bridge-chrome- .zip.sha256).

Tools

Tool	What it does
`onehome_get_user`	Smallest auth probe — returns your OneHome profile (name, email) and the groups your agent shared.
`onehome_get_groups`	List the OneHome "groups" your agent has shared with you (each one a market / curated listing bucket).
`onehome_get_saved_search`	Fetch an agent-curated saved search by id — name, filter criteria, polygon, and the OSK listing ids that compose the share.
`onehome_get_saved_search_with_listings`	The "show me my saved homes" flow in one round trip — saved search plus its inflated listings.
`onehome_search_properties`	Listings within a group; optionally scoped to a saved search.
`onehome_search_suggestions`	Free-text suggestion search (address, MLS #) across all feeds.
`onehome_get_by_address`	Resolve a single free-text street address to a listing's portal URL + id.
`onehome_resolve_addresses`	Bulk-resolve up to 100 structured addresses to portal URLs + listing ids; concurrent, per-row error capture.
`onehome_get_property`	Full property record by listing id or portal URL.
`onehome_bulk_get`	Fetch up to N listings in one call — one structured row per id, per-row error capture.
`onehome_get_property_photos`	Full media gallery — Thumbnail / Medium / Large variants + room descriptions.
`onehome_compare_properties`	2-8 listings side-by-side. Per-row error capture; calls are concurrent.
`onehome_get_schools`	Local-Logic primary + high schools near a lat/lng.
`onehome_get_walk_score`	Local-Logic walk / transit / bike / car friendliness scores.
`onehome_graphql`	Power-user escape hatch — send a raw read-only GraphQL document (queries only; mutations and subscriptions are refused) with variables.
`onehome_calculate_mortgage`	Local PITI calculator. Same math as the other realty MCPs.
`onehome_calculate_affordability`	Local 28/36 DTI solver — max home price you can afford.
`onehome_set_auth`	Add another authenticated session at runtime (magic link / JWT / email-token) for buyers holding shares across multiple agents.
`onehome_set_active_session`	Force a specific registered session to be the active one (overrides MLS-suffix routing).
`onehome_get_session_context`	List every registered session — auth mode, token expiry, and the group / saved-search / agent scope each bootstrapped.
`onehome_healthcheck`	End-to-end auth + GraphQL smoke check with token-expiry diagnostics.

Install

The simplest path is the published Claude plugin (.mcpb install). Its settings take an optional OneHome magic link or bearer token (both stored as sensitive values); leave both blank to use browser-bridge capture instead. For local dev:

git clone https://github.com/chrischall/onehome-mcp

cd onehome-mcp npm install npm run build

Then point your MCP host at node /abs/path/to/onehome-mcp/dist/bundle.js with one of:

// claude_desktop_config.json

{ "mcpServers": { "onehome-mcp": { "command": "node", "args": ["/abs/path/to/onehome-mcp/dist/bundle.js"], "env": { "ONEHOME_MAGIC_LINK": "https://portal.onehome.com/en-US/properties/map?token=eyJ..." } } } }

Development

npm test               # vitest, mocked transport, no network

npm run test:watch npm run test:coverage npx tsc --noEmit npm run build # tsc --noEmit + esbuild → dist/bundle.js

Tests use a FakeTransport (in tests/helpers.ts) that registers per-operationName handlers — there's no live network in the test suite. The tests/index.test.ts smoke check loads the same tool registrations src/index.ts uses against an in-memory MCP client/server pair, so "I wrote the tool file but forgot to wire it up" mistakes fail loudly.
