• src/mcp_paradex/tools/vaults.py:280-313 (handler)

  The main handler function decorated with @server.tool(name="paradex_vault_positions"). It fetches vault positions from the Paradex API using get_paradex_client and api_call, validates with position_adapter, and returns the list of Position objects.
