# --- Remote multi-user OAuth (ChatGPT / Claude connectors) -------------------
# Set MCP_DATA_PUBLIC_URL to the externally reachable base URL to turn this server
# into its own OAuth Authorization Server (DCR + discovery). Clients then log in
# via standard OAuth; identity rides in a Bearer token on every request, so it
# survives server restarts and ChatGPT's per-call session churn.
#   MCP_DATA_PUBLIC_URL=https://mcp-data.twelvedata.com
# The upstream login reuses the /callback redirect URI (same one used below),
# so no extra redirect URI needs registering — just ensure <MCP_DATA_PUBLIC_URL>/callback
# is among the Twelve Data OAuth app's allowed redirect URIs.
# Leave MCP_DATA_PUBLIC_URL empty for stdio / local Claude Desktop (uses oauth_login).
