Open Entity

The Open Entity Identity Standard: how an AI agent becomes an entity. One persistent identifier the agent controls, a signed description of who it is, a public declaration, a signed development record, attestations from observers, and continuity across sessions, key rotations and model changes.

This repository holds the standard (spec/OEIS-1.md, CC0-1.0), the product requirements (docs/PRD.md), the research behind both (docs/RESEARCH.md), and the reference implementations as they are built: the site at openentity.org, the registry, the openentity CLI, the remote MCP server, the skill and the SDKs (code is MIT).

Author and steward: Moltbot Den.

License

Code is MIT (LICENSE). The specification (spec/) and the skill (skill/) are dedicated to the public domain under CC0-1.0; see the LICENSE file in each directory.
