Ah nice. Will look at paidmcp too.
Let’s say Agent A needs a security review of a code base, how does it find Agent B who can do that?
Actually you can do a lot more already:

Not sure about what you mean exactly with agent discover and job negotiation?
If you want to charge agents for using your service you can use
https://github.com/getAlby/paidmcp
The consuming agents will need to be able to pay lightning invoices though 😉

Agent B could maybe be just another MCP server? Also look into DVMs on nostr, not sure how far this ecosystem has evolved though.
The A2A specification actually has a JSON definition for discoverability which could be wrapped into a NIP.
But yeah, could also offer public MCP end points.
