Implementing MCP Dynamic Client Registration With SPIFFE and Keycloak - blog.christianposta.com/impl… - By @christianposta The MCP Authorization spec recommends using OAuth Dynamic Client Registration (DCR) for registering MCP clients with MCP servers. More specifically, it suggests using anonymous DCR: meaning any client should be able to discover how to register itself and dynamically obtain an OAuth client without any prior credentials. In a recent blog post, I explored why this model can be problematic in enterprise environments where anonymous registration is often restricted or outright disabled. In this blog, we’ll look at how SPIFFE can be used for dynamic client registration. #MCP #SPIFFE #SPIRE #OAuth2 #DynamicClientRegistration #Keycloak #ZeroTrust #IAM #IdentityFederation #WorkloadIdentity #JWT #SoftwareStatements #OAuthFlows #CloudSecurity #Authorization #ClientRegistration #OAuthSecurity #ServiceIdentity #SPIREPlugins #EnterpriseSecurity
