Frequently asked questions
OpenClose scores D on Supergood's API Report Card. OpenClose LenderAssist exposes a RESTful API suite to its lenders, but nothing is published and vendors must join the MeridianLink Marketplace under contract to integrate. Since the 2022 acquisition the product is maintained alongside MeridianLink Mortgage with a modest customer base.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
OpenClose is a 100 percent browser based, multi channel mortgage loan origination system sold on a SaaS basis.
Community banks, credit unions, credit union service organizations (for example 7 Mortgage, a CUSO that went live in 2020) and independent mortgage bankers in the United States, plus conduit aggregators such as Ventana Home Mortgage. Loan officers originate in LenderAssist or through ConsumerAssist, processors order credit, flood, MI, appraisal and title from inside the LOS, underwriters condition and decision files, closers generate documents and closing disclosures, and secondary teams lock, hedge and deliver loans (ULDD exports to Fannie Mae and Freddie Mac, MERS registration through eRAMP).
Small install base.
LenderAssist is the system of record for the full loan file: borrower PII and credit, income and asset documents, application and underwriting data, pricing and lock records, closing disclosures, MERS registration data, HMDA fields and investor delivery files.
Founded in 1999 as one of the first SaaS mortgage LOS platforms, OpenClose is fully browser based with no desktop client, which was modern for its era and still compares well with desktop LOS products.
Common alternatives include Encompass (ICE Mortgage Technology), MeridianLink Mortgage, Byte Software, MortgagebotLOS, Mortgage Cadence, LendingPad. Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Not that we could find. As of November 2026 there is no official OpenClose MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. OpenClose doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
