Require org-scoped Langfuse key for Cursor and Hermes MCP - #3
Merged

Conversation
Cursor and Hermes MCP can only list and govern org projects with that key. It is stored in Fusion config (or LANGFUSE_ORG_*), never written into editor MCP files.
…nect. If the key is not already saved or in env, a TTY prompt collects it and writes it to Fusion config before installing Cursor or Hermes MCP.
