CIMD vs DCR explained by Paul, MTS at Anthropic

Описание: The MCP (Model Context Protocol) auth story is changing — and CIMD (Client ID Metadata Documents) is at the center of it.

In this episode, Ravi Madabhushi (Co-founder, Scalekit) sits down with Paul Carleton, Member of Technical Staff at ‪@anthropic-ai‬ and core contributor to the ‪@ModelContextProtocol‬ Working Group, to unpack the latest MCP spec update and why CIMD is emerging as a better alternative to DCR (Dynamic Client Registration) for agent authentication.

Paul shares the real lessons learned from the March and June MCP auth specs, why DCR struggled in open and enterprise environments, and how CIMD fixes core problems around trust, scale, UX, and security for AI agents and MCP servers.

This conversation goes deep into:

Why DCR doesn’t scale for MCP clients and servers
How CIMD enables verifiable, domain-based client identity
What this means for enterprise-ready MCP auth
How Anthropic thinks about agent identity, user consent, and fine-grained authorization
Why URL elicitations and step-up auth matter for safe agent actions
Common mistakes MCP server builders make — and how to avoid them

If you’re building MCP servers, AI agents, or secure tool integrations, this episode explains where MCP auth is heading and why CIMD is a critical upgrade.
