Frequently asked questions
Erwin scores D+ on Supergood's API Report Card. Erwin's primary API (SCAPI) is COM/IDispatch automation inside the Windows desktop app, covering the full model graph. REST exists only at the edges: Mart Server report endpoints with 4 hour bearer tokens, plus separate Evolve and Data Intelligence APIs.
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.
erwin is a portfolio of enterprise data management products owned by Quest Software, anchored on erwin Data Modeler (the flagship, formerly ERwin / CA ERwin / AllFusion ERwin Data Modeler, with a lineage going back to Logic Works in 1988 through Platinum Technology, Computer Associates, and the standalone erwin Inc.
Vertical: misc, Enterprise Data Modeling & Data Intelligence (the closest Supergood-canonical vertical is loosely Enterprise/HR/ERP or GRC/Compliance, but data modeling is its own category and the platform spans every industry). Enterprise data architects open erwin Data Modeler on Windows desktops and build conceptual / logical / physical models, entities, attributes, domains, datatypes, indexes, foreign keys, subject areas, naming standards macros, for new applications or to document existing databases via reverse-engineering against Oracle, SQL Server, PostgreSQL, DB2, Teradata, Snowflake, Databricks, Fabric Lakehouse, Redshift, BigQuery, Azure SQL, MongoDB, Cassandra and JSON/Avro sources.
6/10, erwin Data Modeler is one of the named incumbents in essentially every enterprise data modeling RFP, alongside Idera ER/Studio, SAP PowerDesigner and (for the Oracle stack) Oracle SQL Developer Data Modeler.
Partially, erwin's data is critical *as metadata* but is usually not the runtime operating data of the business.
erwin's lineage runs back to 1988, when Logic Works released ERwin/ERX for the Macintosh and Windows; Platinum Technology acquired Logic Works in 1998; Computer Associates acquired Platinum in 1999 and rebranded the product AllFusion ERwin Data Modeler and later CA ERwin Data Modeler.
Primary API (SCAPI) is COM/IDispatch and runs inside the Windows desktop process, no first-class REST/HTTPS surface for the actual modeling object graph; non-Windows clients are effectively excluded. API documentation is sparse and version-fragmented across r7, r8, 2018 R1, 2019 R1, 2020 R2, 2021 R1, 12.0, 12.5, 13.x, 14.x, 15.x, every release lives at a separate bookshelf URL, and examples of successful code are scarce. Full sourced list under Sources below.
Common alternatives include Idera ER/Studio, SAP PowerDesigner, Oracle SQL Developer Data Modeler, Toad Data Modeler (also Quest), SqlDBM, Hackolade. 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 August 2026 there is no official Erwin 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. Erwin 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.
