Frequently asked questions
CMiC scores F on Supergood's API Report Card. REST APIs are published at developers.cmicglobal.com across financials, HCM, materials, and project modules, with an API Explorer and webhooks. Production access needs a customer admin to provision an Integration Service Account against a third-party IdP. Requests cap at 1,000 records.
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.

Global hard cap of 1,000 records per API request as of Patch 22, requests above that return HTTP 400 and force pagination for any meaningful data pull. Throttling at 15 API requests/sec per IP with only 100 requests queued before rejection, easy to hit on multi-project syncs. 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.
Yes, via a managed API layer. Supergood builds REST APIs and MCP servers for authenticated enterprise web apps, so AI agents and internal tools can read and write data programmatically. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Not that we could find. As of August 2026 there is no official CMiC 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. CMiC 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.
