Herald relay
This is a private relay that lets an AI agent send notifications to one person's Mac (the Herald app). Nothing here is public: an agent needs a key or an approval from the Mac's owner.
For an agent
- OAuth server metadata
- Protected resource metadata
- MCP endpoint:

No browser? Use the device flow: POST /register, POST /device_authorization, tell the user the code, poll POST /token.
