註冊中心已驗證此服務的命名空間屬於 usefulapi.io，且該網域同時執行其端點。這可以確認發布者，但並不代表該服務的工具是安全的。

SourceWeft 的檢查只涵蓋條目是否完整、端點是否回應；不審查伺服器的程式碼，也不審查其工具的行為。

概覽

AI 產生的概覽

把助理連接到 Rex Software 房地產 CRM：搜尋並讀取聯絡人、物件、房產、潛在客戶、租約和交易，並可新增聯絡人、備註或提醒。

可以做什麼: 依姓名或地址自動完成，並搜尋聯絡人、物件和房產
搜尋潛在客戶、估價、租約、交易、行銷活動、活動紀錄和物件事件
搜尋提醒、行程、備註和機構員工使用者
依 id 讀取上述各類紀錄的完整內容
查看可搜尋欄位和值清單，以建立正確的篩選條件
新增個人聯絡人、內部備註或後續提醒
適用情境: 適合讓助理根據 Rex 機構帳戶回答問題或草擬後續事項，例如查找某位聯絡人及其備註、列出某個郊區的待售物件，或查看本週新增的潛在客戶與負責人。
執行需求: 以 URL 方式加入的遠端 MCP 端點；用戶端設定中不要加入 API key 或 Authorization 標頭。透過 OAuth 以使用者的 Rex Software 憑證登入，需選擇區域（澳洲/紐西蘭或英國），必要時填寫帳戶 id。需要具備相應權限的 Rex 帳戶，可能佔用付費機構席次。

安裝前請注意

所要求的聯絡人、房產與租約細節、備註和任務會傳送到所連接的 AI 用戶端及其 LLM 供應商，只應接入你有權在該處處理的紀錄。三個寫入工具會新增聯絡人、備註或提醒；備註和提醒可能對同事可見並觸發機構工作流程，且新增操作不會自動重試，結果不確定時請先在 Rex 核對再重複。用量按次計費：免費每月 50 次呼叫，之後為付費 Pro/Pro+ 方案，透過 Stripe 結帳，供應商費用另計。變更密碼後已簽發的權杖可能仍有效，直到過期或被撤銷。

README

Rex Software MCP by usefulapi

Connect

Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://rex-software.usefulapi.io/mcp.
Claude Code: claude mcp add --transport http rex-software https://rex-software.usefulapi.io/mcp, then run /mcp to log in.
VS Code: Add to VS Code.
Cursor and other clients: add the URL as a remote MCP server:

json

{  "mcpServers": {    "rex-software": {      "url": "https://rex-software.usefulapi.io/mcp"    }  }}

{  "mcpServers": {    "rex-software": {      "url": "https://rex-software.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Rex Software credentials.

Pricing

*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to [email protected].

Pro covers this server only. Subscribe with rex_upgrade (it returns a Stripe Checkout link). Cancel any time with rex_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running rex_upgrade before then undoes the cancel. Or write to [email protected].

Account access and data

Use a dedicated agency-invited integration user with only the privileges needed. It may consume a paid agency seat. Rex Verified Integrator status covers seat-fee benefits and sandbox eligibility; this connection uses the documented ordinary live-account integration flow. Choose Australia/New Zealand or the UK and, if needed, an account id. Vendor charges are separate.

Credentials are encrypted. Requested contacts, property and tenancy details, notes and tasks reach the connected AI client and its LLM provider. Connect only records you are authorized to process there. Disconnect UsefulAPI to stop its connection. Password changes stop new sign-ins; issued tokens may remain valid until vendor expiry/revocation. We request one-hour tokens, but API activity can extend them. Billing follows Rex user id and region across that user's accounts.

Only three writes are exposed: create a person contact, an internal note or a reminder. They require a positive created id to report success. No operation is automatically replayed; check Rex before repeating an uncertain create. Notes/reminders may be visible to agency colleagues and interact with configured workflows. No message-send API is exposed. Reminder completion remains unavailable pending a verified success response.

All 33 tools were checked against current vendor documentation and local mocks. No real customer reads or business writes were tested.

工具

rex_get_user_profile

Get the signed-in Rex user

The Rex user this server is signed in as: user id, name, email, whether they own the account, position and default office. Good first call. POST /v1/rex/UserProfile/read.

無需輸入參數。

rex_list_accessible_accounts

List the Rex accounts the user can access

The Rex agency accounts (account_id and name) this user can sign in to. A user with several accounts picks one with the Account id field when connecting. POST /v1/rex/UserProfile/getAccessibleAccounts.

無需輸入參數。

rex_describe_search_fields

List the search fields of a Rex service

The field names a search on the given service accepts in criteria, each with its label, type and (for enums) the value list. Call this before building criteria on a field you are not sure of. Sorting (order_by) uses a separate list of sortable fields whose names can differ (for example name_last, not contact.name_last): set include_order_by to get it. POST /v1/rex/<Service>/describeSearchFields (and <Service>/describeModel for include_order_by).

輸入參數matchservice必填include_order_by

rex_list_value_lists

List the Rex value lists

The names of Rex's value lists (the allowed ids for fields such as note types, reminder types, lead sources and property categories). Use a name with rex_get_value_list. POST /v1/rex/SystemValues/getValueCategories.

無需輸入參數。

rex_get_value_list

Get the values of a Rex value list

The allowed values (id and label) of one value list, for example property_category. The ids are what writes and criteria expect. POST /v1/rex/SystemValues/getCategoryValues.

輸入參數list_name必填

rex_autocomplete_contacts

Find contacts by name

Quick lookup of contacts by (part of) a name: returns the best matches with id, name, email and phone. Use the id with rex_get_contact. POST /v1/rex/Contacts/autocomplete.

輸入參數limitsearch_string必填

rex_autocomplete_listings

Find listings by address

Quick lookup of listings by (part of) an address: returns the best matches with listing id and address. Use the id with rex_get_listing. POST /v1/rex/Listings/autocomplete.

輸入參數limitsearch_string必填listing_states

rex_search_contacts

Search contacts

Search contacts (people and companies). Filters (criteria) combine with AND; results are paged with offset/limit (next_offset says where to continue). Useful fields: contact.name_full, contact.name_first, contact.name_last, contact.email_address, contact.phone_number, contact.type, contact.tags, contact.interest_level, contact.last_contacted_date, system_modtime. To find someone by name, rex_autocomplete_contacts is simpler. POST /v1/rex/Contacts/search.
