+  Index tools for intents, networks, and opportunities. Disclosure — registers
+  an index gateway platform. Login writes INDEX_SESSION_TOKEN to the Hermes
+  env. When this install is the selected negotiator, a Bun child from PATH
+  runs the pinned bundle and mints INDEX_API_KEY from that session if it is
+  missing; that key also registers the Index MCP server. API traffic goes to
+  protocol.index.network. The desktop half ships as desktop/plugin.js and
+  stays off until enabled.
