Copper Banking

Copper (Copper Banking) is a Seattle-based consumer fintech founded in 2019 by Eddie Behringer and Stefan Berglund that began as a teen banking app and debit card built on the Synapse banking-as-a-service platform. After Synapse's collapse Copper abruptly discontinued its bank deposit accounts and debit cards in May 2024 and repositioned as a financial-empowerment and earning app, where members earn cash and gift-card rewards through cash back, surveys, receipt scanning, games and referrals, alongside financial-literacy content, guides and in-school workshops. Copper publishes no public developer portal, documentation or API specification; the only machine-readable surface reachable without credentials is an OAuth 2.0 authorization server for a Model Context Protocol endpoint at mcp.getcopper.com.

Copper Banking publishes 1 API on the APIs.io network. Tagged areas include Company, Financial Services, Fintech, Consumer Finance, and Financial Literacy.

Copper Banking’s developer surface includes engineering blog, support, authentication, and 12 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.

  description: An undocumented Model Context Protocol server operated by Copper at mcp.getcopper.com. The host publishes RFC
    8414 OAuth 2.0 Authorization Server Metadata at /.well-known/oauth-authorization-server declaring the `mcp` and `offline_access`
    scopes, authorization-code grant with PKCE (S256), refresh tokens, and RFC 7591 dynamic client registration. The MCP transport
    endpoint itself was not discoverable at any conventional path anonymously, so the tool list and input schemas could not
    be introspected. Copper publishes no documentation for this surface.
