Clara Mortgage Assistant is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
refuse_unsupported_mortgage_requestReturns a fixed explanation that a request is outside this calculator's scope, with a calculation it can do instead. Categories: approval or underwriting decisions, lender or product recommendations, borrower documents or accounts, current rates, rules, or thresholds, external accompare_mortgage_scenariosCompares up to six Canadian fixed-rate payment and amortization scenarios using deterministic calculations. Works only from explicit, non-identifying numbers in the request. Returns calculations only: no approval, underwriting, or suitability decisions, no lender or product recomcalculate_qualificationCalculates the B-20 qualifying rate, the qualifying payment, and the resulting GDS/TDS from a principal, contract rate, amortization, and income. It computes the payment itself, so it needs those loan terms. Results are neutral scenario math, not an approval or underwriting deciscalculate_debt_serviceCalculates Canadian GDS and TDS ratios from a monthly mortgage payment that is already known, plus income, housing costs, and other monthly debts. It takes the payment as given and needs no principal, rate, or amortization. Ratios are not an approval or suitability decision. Workcalculate_ltvCalculates Canadian loan-to-value and combined loan-to-value from the loan amount, other secured positions, and a purchase price, an appraised value, or both. Ratios are not an approval or suitability decision. Works only from explicit, non-identifying numbers in the request.
