Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

NameDescription
ONEHOME_TOKEN
Optional		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
Optional		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
Optional		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
Optional		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
Optional		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
Optional		Absolute path where the fetchproxy long-term identity keypair is stored (default ~/.fetchproxy/identity/).
