MCP

One MCP session, both toolsets

One session gives your product or agent every eBay and ERPNext tool at once — connect once, list tools, and call them like any single-app session.

// One external user owns both connected accounts, so either app's tools
// run on their behalf with the same externalUserId.

# Connect both accounts to the same external_user_id, then

ARCHITECTURE

One user, two connected accounts

Your user connects each account once, under whatever ID they already have in your product. The two stay independent — either can be revoked on its own — and your code reaches both through that one user.
