      MCP is terrific, one big thing missing: Strong Identity

      The agentic workflows of the future cannot be built without strong identity. The MCP-I specification offers an open proposal to bring 
strong identity to MCP.

      The MCP specification has laid a solid foundation for how agents communicate with servers. But as we've worked with real-world use cases, one critical piece has stood out as missing: identity. Without a robust identity model, agents can't truly act autonomously or securely. The MCP-I (I for Identity) specification addresses this gap—introducing a practical, interoperable approach to agentic identity. We've developed MCP-I in the spirit of collaboration, with deep respect for the groundwork laid by teams like Anthropic, and with the hope that this helps move the ecosystem forward.

      Here’s how MCP-I closes critical gaps:

      Authentication — Made Foundational
      Authentication — Made Foundational

      MCP only briefly references authentication.  But real-world workflows will need much stronger identity.  MCP-I solves these issues.
      Tell Good From Bad Agents
      Tell Good From Bad Agents
      Long experience has taught us that a system that assumes all actors are good actors will fail.  We need a way to tell malicious agents apart from good.  MCP-I provides built-in agent reputation systems to tell good from bad.
      Manage Human To Non-Human Authority Grants
      Manage Human To Non-Human Authority Grants

      We need a way to track what authorities that humans (or other entities) have granted to agents.  It needs to be fine-grained to support varied roles.  MCP-I provides this framework.
      Framework For Legal Agreements
      Framework For Legal Agreements

      Most real-world workflows include acceptance of agreements.  Think the "click wrap" checkboxes we see everywhere.  You can't proceed without clicking them.  But agents can't make these agreements on behalf of a human.  MCP-I provides a framework to solve this problem.

      MCP-I is designed to be a lightweight addition to MCP.  We add a simple preamble to establish strong identity, then the MCP conversation continues as normal.
