This isn’t added yet but would be pretty easy to do!

Currently the tools in this MCP only read and query from relays but you could add some simple tools to create identity, create notes, and broadcast notes.

Each chat could create its own ephemeral identity (or you could pass nsec to the LLM in the prompt to have a consistent identity?)
