GET and POST were probed against /, /mcp, /mcp/, /sse, /mcp/sse, /messages, /mcp/messages, /api/mcp, /v1/mcp, /rpc, /server, /stream, /http, /v1, /copper, /api and /tools — every one returned an Express 404 ("Cannot GET|POST "). The endpoint is either at a non-guessable or per-tenant path, or is only issued to a client after the OAuth dance. No URL is recorded rather than guessing one. evidence_of_server: - Dedicated mcp.getcopper.com subdomain resolves (35.241.5.244); getcopper.com has no DNS wildcard, so the record was deliberately created. - RFC 8414 OAuth 2.0 Authorization Server Metadata served at /.well-known/oauth-authorization-server with HTTP 200, application/json. - scopes_supported is exactly ["mcp", "offline_access"] — the `mcp` scope names the protected resource. - /authorize, /token and /register are all live and return structured OAuth error objects on malformed input (400 invalid_request / 400 invalid_client_metadata / 405 method_not_allowed), i.e. a working authorization server, not a placeholder. authorization: issuer: https://mcp.getcopper.com/ authorization_endpoint: https://mcp.getcopper.com/authorize token_endpoint: https://mcp.getcopper.com/token registration_endpoint: https://mcp.getcopper.com/register dynamic_client_registration: true grant_types: [authorization_code, refresh_token] pkce: [S256] scopes: [mcp, offline_access] document: well-known/copper-banking-oauth-authorization-server.json tools: [] tools_note: >- tools/list could not be called: the transport endpoint was not reachable anonymously and the server is OAuth-protected. The real tool set and inputSchemas require an authenticated introspection with a client registered at the registration_endpoint. No tools are listed rather than deriving a candidate set — Copper publishes no OpenAPI to derive them from. x-evidence: fetched: '2026-08-04' url: https://mcp.getcopper.com/.well-known/oauth-authorization-server http_status: 200 content_type: application/json; charset=utf-8
