CINC Systems API
CINC has a documented V1 REST API with OAuth 2.0 client credentials, but CINC hands out the client ID and secret and third-party vendors go through partner approval. Docs are thin, the full Swagger sits behind the customer login, and there are no webhooks.
Frequently asked questions
CINC Systems scores D+ on Supergood's API Report Card. CINC has a documented V1 REST API with OAuth 2.0 client credentials, but CINC hands out the client ID and secret and third-party vendors go through partner approval. Docs are thin, the full Swagger sits behind the customer login, and there are no webhooks.
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.
CINC Systems is a cloud accounting, banking-integration and community management platform for HOA and condominium management companies.
Real Estate & Property; community association (HOA and condo) management companies of all sizes, from single-office firms to national portfolios.

Founded 2005 as a web application, with a legacy CINCWEB homeowner portal that reviewers say limited functionality until a newer web product rolled out.
Support tickets get closed before resolution and navigation has no logic, with many steps for simple tasks. No audit trail for transactions, custom reporting is not user friendly and some reports cannot be exported to Excel. Full sourced list under Sources 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. There is no official CINC Systems 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. CINC Systems 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.
