The MCP now uses T3's desktop connections by default. Register t3code-thread-mcp with no arguments or tokens. Explicit direct-connection configuration still takes precedence.
Install:
npm install -g https://github.com/samdickson22/t3code-thread-mcp/releases/download/v0.3.0/t3code-thread-mcp-0.3.0.tgz
Desktop discovery requires a running T3 build containing pingdotgg/t3code#12148. This upstream change is not merged yet. Desktop mode supports macOS/Linux; Windows can use direct connections.
17 existing tests pass. Verified real Astra/Fable thread creation, messaging, settlement, and revival between a Mac mini and physical MacBook Air through T3 Connect. Screenshot attached.
