OAuth, CIMD and ID-JAG
CIMD server resolution, ID-JAG mint and redeem, RFC 9207 issuer handling, client creation and a dual-era OAuth-protected MCP server binding are implemented and tested in VerifableSystem. On 10 August 2026, Lumoin committed Verifable to the OpenID AIIM MCP Security Interoperability Event. The current /mcp/{segment} binding builds five tools: resolve_did, sparql_query, public dpp_chain_walk, governed product_passport_get and recent_calls, which returns only the caller's own recent MCP calls. Every realm is served all five except the public interoperability realm, which is served resolve_did alone. The passport read derives caller, tenant, represented principal and disclosure tier from the validated token, applies AuthZEN and records trace-linked dpp.passport.read action evidence. This public origin advertises no callable endpoint; the authorization server, OpenID Provider, MCP endpoints and actors' client ID metadata documents are deployed at https://trust.verifable.eu. Flows run: our MCP client with partners' authorization servers and MCP servers, on the OAuth, CIMD and Enterprise-Managed Authorization formats; our OpenID Provider issuing the identity assertion authorization grant (ID-JAG), on the Enterprise-Managed Authorization format; our authorization server redeeming a partner provider's ID-JAG, on the Enterprise-Managed Authorization format; our authorization server admitting partners' clients by their client ID metadata documents, on the CIMD format; our MCP server with partners' clients, on the OAuth format. The event's MCP interoperability results prove the capabilities these flows exercise until the official results are published; this page is updated again then. The governed product_passport_get read is proven by the server's integration tests, not by the event's results. Partners run with: 11/11 AI, Auth0, AWS, Cayosoft, CK SaaS, Datawiza, Descope, Geobeyond, Helisoft, Minority Prophet, Nxtlinq, Saviynt, SecureAuth and WSO2. The full product contract keeps represented authority, per-operation policy, permitted disclosure and attributable evidence together whenever a governed product operation is bound. Commitment is not certification.
