No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.

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.

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 <jwt> attached. We support three ways to source that bearer:

Mode	How to enable	Notes
`env_token`	`ONEHOME_TOKEN=<jwt>`	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) + fetchproxy extension installed + signed-in `portal.onehome.com` tab	We wait for your tab to fire any GraphQL request, snapshot the Authorization header, and reuse it.
